As generative AI becomes increasingly integrated into various industries, it is essential to consider the ethical implications of its use. What are some ethical considerations when using generative AI? This technology, while offering incredible potential, also presents challenges such as privacy concerns, bias, accountability, and the risk of misinformation. Addressing these issues is crucial for ensuring that generative AI serves as a beneficial and responsible tool in our society.

Understanding generative AI

Generative AI, a subset of artificial intelligence, is revolutionizing numerous industries by creating new content autonomously. This technology, which leverages machine learning algorithms to generate text, images, music, and even code, is becoming an integral part of our digital landscape. According to a recent report by McKinsey, the AI industry could deliver up to $13 trillion in additional global economic activity by 2030, highlighting its profound impact and potential .

What is generative AI?

At its core, generative AI refers to systems capable of producing new data that mimics the patterns of the data they were trained on. Unlike traditional AI, which is typically used for tasks like classification and prediction, generative AI creates novel content. For instance, OpenAI’s GPT-4 can write essays, answer questions, and even generate creative fiction, while GANs (Generative Adversarial Networks) are used to create realistic images and videos.

Examples of generative AI include text generation models like OpenAI’s GPT series, image generation models like DALL-E, and music composition models such as Jukedeck. These technologies utilize deep learning techniques, particularly neural networks, to analyze and learn from vast amounts of data, enabling them to produce new, coherent outputs that are often indistinguishable from human-created content.

Applications of generative AI

The applications of generative AI are vast and varied, touching nearly every sector. In the art world, AI is being used to create original paintings and sculptures, challenging our traditional notions of creativity and authorship. For example, in 2018, a portrait generated by a GAN was sold at Christie’s for $432,500, demonstrating the commercial viability of AI-generated art.

In entertainment, AI is transforming the way we produce and consume media. AI-generated scripts, music, and even entire virtual influencers are becoming commonplace. Companies like Amper Music and AIVA (Artificial Intelligence Virtual Artist) are at the forefront of using AI to compose music for movies, games, and advertising.

The business sector is also reaping the benefits of generative AI. From automating content creation for marketing campaigns to designing innovative products, AI is streamlining processes and boosting productivity. For instance, Coca-Cola has used AI to generate marketing content, improving engagement and reducing production costs .

Healthcare is another critical area where generative AI is making strides. AI models are being used to create synthetic medical data to train other AI systems, enhancing diagnostic accuracy without compromising patient privacy. Furthermore, generative AI is aiding in drug discovery by simulating molecular structures and predicting their interactions, significantly accelerating the development of new medications.

As generative AI continues to evolve, its applications will undoubtedly expand, bringing both opportunities and challenges that we must navigate with care and responsibility.

Privacy concerns

As generative AI continues to advance, concerns about privacy have come to the forefront. These technologies often rely on vast amounts of data to function effectively, raising significant questions about data privacy and security.

Data privacy issues

Generative AI models require extensive datasets to train, which frequently include personal and sensitive information. The use of such data presents risks, particularly if it is not properly anonymized or if the AI inadvertently generates outputs that reveal private information. A report by the World Economic Forum highlights that data privacy is one of the top concerns in AI development, emphasizing the need for stringent data protection measures.

Risks related to training AI models with personal data

When AI models are trained on datasets containing personal information, there is a risk that the generated content could expose private details. For example, language models like GPT-4 can unintentionally regurgitate sensitive information that was part of their training data. This raises significant privacy issues, especially if the AI is used in applications where confidentiality is paramount, such as healthcare or finance.

Ensuring data protection

To mitigate these risks, it is crucial to implement robust data protection strategies. One approach is to use differential privacy, which adds noise to the data to obscure individual entries while still allowing the AI to learn from the overall dataset. This technique helps protect individual privacy without compromising the model’s performance. Additionally, adhering to regulations such as the General Data Protection Regulation (GDPR) ensures that data is collected and used in a manner that respects user privacy.

Intellectual property and copyright

Generative AI also brings complex intellectual property (IP) and copyright challenges. As AI systems generate new content, questions arise about ownership and the potential for copyright infringement.

Copyright challenges

One of the primary concerns is whether AI-generated content infringes on existing copyrights. Since AI models are trained on vast amounts of data, they might inadvertently produce content that closely resembles existing works, leading to potential legal disputes. For instance, there have been instances where AI-generated music or art closely mirrored existing pieces, raising questions about originality and copyright infringement.

Ownership of AI-created works

Determining who owns the rights to AI-generated content is another contentious issue. Traditionally, copyright law grants ownership to human creators, but with AI-generated works, the situation becomes less clear. Some jurisdictions, like the United States, do not recognize AI as an author, thereby leaving the rights to the user or developer of the AI. However, this approach is not universally accepted, and ongoing legal debates continue to shape the landscape.

Legal precedents and case studies

Several legal cases have begun to address these issues. For example, in the UK, the case of Infopaq International A/S v. Danske Dagblades Forening set a precedent by ruling that originality in copyright law requires a “human intellectual creation.” This ruling implies that AI-generated works may not qualify for copyright protection unless significant human input is involved. Additionally, companies like OpenAI have started to navigate these waters by licensing their models and generated content under specific terms to clarify usage rights.

As we continue to harness the power of generative AI, it is imperative to address these privacy and intellectual property concerns proactively. By developing robust frameworks and adhering to ethical guidelines, we can ensure that AI development progresses responsibly and sustainably.

Bias and fairness

As generative AI becomes increasingly integrated into various sectors, concerns about bias and fairness in AI-generated content have grown. Addressing these issues is crucial to ensure that AI technologies do not perpetuate or exacerbate existing societal inequalities.

Potential for bias

AI-generated content can be biased due to the data it is trained on. If the training data reflects existing biases, the AI will likely reproduce and even amplify these biases in its outputs. For instance, language models trained on internet text can inherit gender, racial, and cultural biases present in the data. According to a study by MIT, bias in AI systems can result in discriminatory outcomes, affecting everything from job recruitment processes to law enforcement practices.

Impact on marginalized communities

Biased AI content can have a profound impact on marginalized communities, reinforcing stereotypes and perpetuating discrimination. For example, facial recognition technologies have been shown to have higher error rates for people with darker skin tones, leading to potential misidentifications and unjust consequences. Similarly, biased language models can produce content that is harmful or exclusionary to certain groups, perpetuating societal inequities and diminishing trust in AI systems.

Mitigating bias

To reduce bias in AI training and output, several methods can be employed. One effective approach is to ensure diverse and representative training datasets. Additionally, incorporating fairness constraints into the AI’s learning process can help mitigate bias. Techniques such as re-weighting training data, debiasing algorithms, and conducting regular bias audits are also essential. Engaging in transparent practices and involving diverse teams in AI development can further help in creating fairer AI systems.

Accountability and transparency

Accountability and transparency are fundamental to the ethical use of generative AI. Clear AI algorithms and processes are necessary to build trust and ensure responsible use.

Importance of transparency

Transparency in AI algorithms and processes allows stakeholders to understand how decisions are made and to identify potential biases or errors. This clarity is crucial for building trust and ensuring that AI systems are used ethically. For instance, the European Union’s AI Act emphasizes the need for transparency in AI development, requiring developers to provide detailed documentation of their algorithms.

Establishing accountability

Establishing accountability involves defining who is responsible for the outcomes of AI-generated content. This includes both the developers who create the AI models and the users who deploy them. Clear accountability frameworks help ensure that AI is used responsibly and that there are mechanisms in place to address any negative consequences. Organizations like OpenAI have started implementing internal and external review processes to uphold accountability standards.

Role of regulatory bodies

Regulatory bodies play a critical role in ensuring ethical AI use. They provide guidelines and frameworks that set standards for transparency, accountability, and fairness. For example, the General Data Protection Regulation (GDPR) in Europe includes provisions that affect AI, such as the right to explanation, which mandates that individuals can request an explanation of decisions made by automated systems.

Misinformation and deepfakes

One of the most significant risks associated with generative AI is the potential for generating misinformation and deepfakes, which can have serious implications for public trust and security.

Risks of misinformation

AI-generated misinformation can spread rapidly, making it difficult to discern truth from falsehood. Deepfakes, which are hyper-realistic AI-generated videos and images, can be used to impersonate individuals, manipulate public opinion, and spread false information. The impact of misinformation can be profound, affecting elections, public health, and social stability.

Implications for public trust

The proliferation of AI-generated misinformation can erode public trust in digital content and media. When people cannot distinguish between real and fake information, it undermines the credibility of legitimate sources and creates a general sense of distrust. This can have far-reaching consequences for democratic processes and societal cohesion.

Detecting and counteracting harmful content

To combat the risks of misinformation and deepfakes, several approaches can be implemented. Developing advanced detection algorithms to identify deepfakes and false information is critical. Additionally, promoting media literacy and critical thinking skills among the public can help individuals discern credible information from falsehoods. Platforms like Facebook and Twitter have started using AI to detect and remove deepfakes, while also partnering with fact-checking organizations to verify content.

Eco-friendly alternatives

Exploring greener options for AI development includes the use of sustainable practices and innovative technologies. Techniques like federated learning, which distributes the training process across multiple devices, can reduce the overall energy consumption. Additionally, researchers are investigating the use of more energy-efficient hardware, such as neuromorphic chips that mimic the human brain’s energy-efficient processing capabilities. These approaches can help mitigate the environmental impact while advancing AI technologies.

Human-AI collaboration

Ethical considerations in human-AI collaboration are crucial to ensure that AI enhances human capabilities without undermining human autonomy or creativity.

Ethical partnerships

Human-AI creative collaborations require careful consideration of ethical implications. It is important to ensure that AI tools are used to support and augment human creativity rather than replace it. This involves fostering partnerships where AI acts as an assistant, providing new insights and capabilities while leaving the final creative decisions to humans. For instance, artists using AI to generate new forms of art still retain control over the creative process, ensuring that their unique vision and expertise are central to the final output.

Ensuring human oversight

Maintaining human oversight in AI decision-making processes is essential to prevent unintended consequences and ensure ethical use. Human oversight ensures that AI systems are used responsibly and that any decisions made by AI can be reviewed and corrected if necessary. This is particularly important in high-stakes applications, such as healthcare and finance, where the consequences of AI decisions can be significant. Regulatory guidelines, such as those from the European Commission, emphasize the need for human oversight in AI systems to ensure accountability and ethical use.

Enhancing human creativity

Using AI to augment human skills involves leveraging AI’s capabilities to enhance rather than replace human creativity and expertise. AI can provide new tools and perspectives that enable humans to push the boundaries of what is possible in their fields. For example, AI-powered design tools can help architects explore innovative building designs, while AI-assisted writing tools can provide authors with new ways to develop their narratives. By enhancing human creativity, AI can serve as a powerful partner in innovation and artistic expression.

Addressing the environmental impact and ethical considerations of human-AI collaboration is essential for the responsible advancement of generative AI. By adopting sustainable practices and fostering ethical partnerships, we can ensure that AI serves as a force for good, enhancing human capabilities and contributing to a sustainable future.

What are the risks of generative AI?

Overview of potential risks

Generative AI poses several potential risks, including the creation of harmful or misleading content, perpetuation of biases, and threats to privacy and security. For instance, AI-generated deepfakes can create realistic but false images or videos, leading to misinformation and potential harm. The Gartner report predicts that by 2022, most people in mature economies will consume more false information than true information, highlighting the urgent need to address these risks.

Examples of unintended consequences

Ethical dilemmas and unintended outcomes are common with generative AI. For example, AI algorithms can inadvertently create biased or discriminatory content if trained on unrepresentative data. Additionally, the misuse of AI-generated content can lead to reputational damage, financial loss, or even legal issues. A notable case involved an AI model that generated discriminatory hiring recommendations, sparking widespread concerns about bias in AI decision-making processes.

Preventative measures

To minimize these risks, several preventative measures can be implemented. First, developing and adhering to robust ethical guidelines is essential. This includes conducting thorough bias audits, ensuring transparency in AI processes, and implementing strict data privacy measures. Additionally, ongoing monitoring and evaluation of AI systems can help identify and address issues promptly. Collaboration between AI developers, ethicists, and regulatory bodies is also crucial for creating comprehensive frameworks that promote the responsible use of AI.

As we continue to rely more on AI-powered technologies, it’s mandatory to address the issue of bias in machine learning. Bias can be present in many different forms, ranging from subtle nuances to more obvious patterns. Unfortunately, this bias can easily seep into machine learning algorithms, creating significant challenges when it comes to developing fair, transparent, and impartial decision-making procedures.

The challenge of bias is particularly acute in industries that are already prone to bias and discrimination, such as those related to hiring, finance, and criminal justice. For example, if a machine learning algorithm is trained on data that is biased against a certain group of people, it will inevitably produce biased results. This can have serious consequences, such as perpetuating discrimination and injustice.

To address these issues, it’s important to develop machine learning algorithms that are designed to be as impartial as possible. This requires careful attention to the data used to train the algorithms, as well as the algorithms themselves.

What is bias in machine learning?

Bias in machine learning refers to the systematic and unjust favoritism or prejudice shown by algorithms towards certain groups or outcomes. The foundation of bias lies in society’s visions and values, which can unintentionally taint the data used to train AI models.

This unintentional influence from human biases can result in the perpetuation of discriminatory practices, hindering the true potential of AI in advancing society.

There are different types of machine learning bias to be aware of including:

• Sample bias
• Prejudice bias
• Measurement bias
• Aggregation bias

Sample bias: Occurs when the training dataset is not representative of the real-world population, leading the model to perform poorly on certain groups.

Prejudice bias: Arises when data contains prejudiced attitudes or beliefs that favor one group over another, perpetuating inequalities.

Measurement bias: Results from incorrect or skewed data measurements, leading to inaccurate conclusions.

Aggregation bias: Emerges when different datasets are combined without accounting for variations in data sources, leading to distortions in the model’s understanding.

The first step to completely solving any problem is to understand the absolute underlying cause. Bias is a concept that rightly plagues many minorities today, and many researchers are trying to understand how it is rooted in human psychology.

Research in social psychology has shown that individuals may hold implicit biases, which are unconscious attitudes and stereotypes that influence their judgments and behaviors. Studies have demonstrated that people may exhibit implicit racial biases, where they associate negative or positive traits with specific racial or ethnic groups. Implicit bias can influence decision-making, interactions, and behavior, leading to unintentional discrimination and perpetuation of stereotypes.

It is quite possible that this fallacy in human psychology is at the root of bias in machine learning. If an AI developer intentionally or unintentionally excludes certain groups from the master dataset used to train ML algorithms, the result will be that the AI will struggle to interpret them. Machine learning is growing exponentially and while this is a correctable error in the early stages, this mistake will gradually be accepted as a fact by AI, ultimately leading to bias in machine learning.

Bias in machine learning is a major threat to both society and AI

The presence of bias in machine learning can have far-reaching consequences, affecting both the very foundation of AI systems and society itself. At the core of machine learning lies the ability to make accurate predictions based on data analysis. However, when bias seeps into the training data, it compromises the accuracy and reliability of machine learning models. Biased models may produce skewed and misleading results, hindering their capability to provide trustworthy predictions.

The ethics and risks of pursuing artificial intelligence

The consequences of bias in machine learning go beyond just inaccurate predictions. Biased models can produce results that misrepresent future events, leading people to make decisions based on incorrect information and potentially causing negative consequences.

When bias is unevenly distributed within machine learning models, certain subgroups may face unfair treatment. This can result in these populations being denied opportunities, services, or resources, perpetuating existing inequalities.

Transparency is key in building trust between users and AI systems. However, when bias influences decision-making, the trustworthiness of AI is called into question. The obscurity introduced by bias can make users question the fairness and intentions of AI technologies.

One of the most concerning impacts of bias in machine learning is its potential to produce unjust and discriminatory results. Certain populations may be subjected to biased decisions, leading to negative impacts on their lives and reinforcing societal prejudices.

Bias in training data can hinder the efficiency of the machine learning process, making it more time-consuming and complex to train and validate models. This can delay the development of AI systems and their practical applications.

Interestingly, bias can lead to overcomplicated models without necessarily improving their predictive power. This paradox arises when machine learning algorithms try to reconcile biased data, which can ultimately inflate model complexity without any significant improvements in performance.

Evaluating the performance of biased machine learning models becomes increasingly difficult. Distinguishing between accuracy and prejudice in the outputs can be a daunting task, making it hard to determine the true effectiveness of these AI systems.

As bias infiltrates machine learning algorithms, their overall performance can be negatively impacted. The effectiveness of these algorithms in handling diverse datasets and producing unbiased outcomes may suffer, limiting their applicability.

Bias in machine learning can significantly impact the decisions made based on AI-generated insights. Instead of relying on objective data, biased AI systems may make judgments based on prejudiced beliefs, resulting in decisions that reinforce existing biases and perpetuate discriminatory practices.

Can a biased model be recovered?

The discovery of bias in machine learning models raises critical questions about the possibility of recovery. Is it feasible to salvage a biased model and transform it into an equitable and reliable tool?

To address this crucial issue, various strategies and techniques have been explored to mitigate bias and restore the integrity of machine learning algorithms.

Determine the cause

A fundamental step in recovering a biased model is to identify the root cause of bias. Whether the bias originates from biased data collection or the algorithm design, pinpointing the sources of bias is crucial for devising effective mitigation strategies.

By understanding the underlying reasons for bias, researchers and developers can adopt targeted approaches to rectify the issue at its core.

Measure the degree of bias

To effectively tackle bias, it is essential to quantify its extent and severity within a model. Developing metrics that can objectively measure bias helps researchers grasp the scale of the problem and track progress as they implement corrective measures.

Accurate measurement is key to understanding the impact of bias on the model’s performance and identifying areas that require immediate attention.

How does it affect?

Bias in machine learning can have varying effects on different groups, necessitating a comprehensive assessment of its real-world implications. Analyzing how bias affects distinct populations is vital in creating AI systems that uphold fairness and equity.

This assessment provides crucial insights into whether certain subgroups are disproportionately disadvantaged or if the model’s performance is equally reliable across various demographics.

Start from the scratch

High-quality data forms the bedrock of accurate and unbiased machine learning models. Ensuring data is diverse, representative, and free from biases is fundamental to minimizing the impact of prejudice on the model’s predictions.

Rigorous data quality checks and data cleaning processes play a vital role in enhancing the reliability of the model but if the degree of bias in machine learning is too high, starting with a new root dataset must be the way to go.

To cultivate fairness and inclusivity within machine learning models, expanding the training dataset to include a wide range of examples is paramount. Training on diverse data enables the model to learn from a variety of scenarios, contributing to a more comprehensive understanding and improved fairness across different groups.

Change it if you can’t save it

Machine learning offers a plethora of algorithms, each with its strengths and weaknesses. When faced with bias, exploring alternative algorithms can be an effective strategy to find models that perform better with reduced bias.

By experimenting with various approaches, developers can identify the algorithms that align most closely with the goal of creating unbiased AI systems.

No need to be a detective

We have repeatedly mentioned how big a problem bias in machine learning is. What would you say if we told you that you can make AI control another AI?

To ensure your ML model is unbiased, there are two approaches: proactive and reactive. Reactive bias detection happens naturally when you notice that a specific set of inputs is performing poorly. This could indicate that your data is biased.

Alternatively, you can proactively build bias detection and analysis into your model development process using a tool. This allows you to search for signs of bias and gain a better understanding of them.

Several tools can help with this, such as:

• Google What-If
• IBM AI Fairness 360
• FairML
• Lightly

These tools provide features like visualizing your dataset, analyzing model performance, assessing algorithmic fairness, and removing redundancy and bias introduced by the data collection process. By using these tools, you can minimize the risk of bias in machine learning.

Addressing bias in machine learning models is a significant challenge, but it is not impossible to overcome. A multifaceted approach can help, which involves identifying the root cause of bias, measuring its extent, exploring different algorithms, and improving data quality.

Even state-of-the-art automatic speech recognition (ASR) algorithms struggle to recognize the accents of people from certain regions of the world. That’s the top-line finding of a new study published by researchers at the University of Amsterdam, the Netherlands Cancer Institute, and the Delft University of Technology, which found that an ASR system for the Dutch language recognized speakers of specific age groups, genders, and countries of origin better than others.

Speech recognition has come a long way since IBM’s Shoebox machine and Worlds of Wonder’s Julie doll. But despite progress made possible by AI, voice recognition systems today are at best imperfect — and at worst discriminatory. In a study commissioned by the Washington Post, popular smart speakers made by Google and Amazon were 30% less likely to understand non-American accents than those of native-born users. More recently, the Algorithmic Justice League’s Voice Erasure project found that that speech recognition systems from Apple, Amazon, Google, IBM, and Microsoft collectively achieve word error rates of 35% for African American voices versus 19% for white voices.

The coauthors of this latest research set out to investigate how well an ASR system for Dutch recognizes speech from different groups of speakers. In a series of experiments, they observed whether the ASR system could contend with diversity in speech along the dimensions of gender, age, and accent.

The researchers began by having an ASR system ingest sample data from CGN, an annotated corpus used to train AI language models to recognize the Dutch language. CGN contains recordings spoken by people ranging in age from 18 to 65 years old from Netherlands and the Flanders region of Belgium, covering speaking styles including broadcast news and telephone conversations.

CGN has a whopping 483 hours of speech spoken by 1,185 women and 1,678 men. But to make the system even more robust, the coauthors applied data augmentation techniques to increase the total hours of training data “ninefold.”

When the researchers ran the trained ASR system through a test set derived from the CGN, they found that it recognized female speech more reliably than male speech regardless of speaking style. Moreover, the system struggled to recognize speech from older people compared with younger, potentially because the former group wasn’t well-articulated. And it had an easier time detecting speech from native speakers versus non-native speakers. Indeed, the worst-recognized native speech — that of Dutch children — had a word error rate around 20% better than that of the best non-native age group.

In general, the results suggest that teenagers’ speech was most accurately interpreted by the system, followed by seniors’ (over the age of 65) and children’s. This held even for non-native speakers who were highly proficient in Dutch vocabulary and grammar.

As the researchers point out, while it’s to an extent impossible to remove the bias that creeps into datasets, one solution is mitigating this bias at the algorithmic level.

“[We recommend] framing the problem, developing the team composition and the implementation process from a point of anticipating, proactively spotting, and developing mitigation strategies for affective prejudice [to address bias in ASR systems],” the researchers wrote in a paper detailing their work. “A direct bias mitigation strategy concerns diversifying and aiming for a balanced representation in the dataset. An indirect bias mitigation strategy deals with diverse team composition: the variety in age, regions, gender, and more provides additional lenses of spotting potential bias in design. Together, they can help ensure a more inclusive developmental environment for ASR.”

At first thought, predictive analytics engines seem like an ideal way to remove human bias from decision-making. After all, these models draw conclusions from data, not stereotypes, so they should be objective in theory. While this seems reasonable at first, researchers discovered that predictive analytics could indeed carry human biases and amplify them.

Perhaps the most famous example of AI bias is Amazon’s failed recruitment algorithm. Developers found that the model taught itself to prefer male candidates since they trained it mostly on men’s resumes. Implicit biases that humans may not recognize within themselves can transfer to the algorithms they program.

As companies start to use predictive analytics in areas like creditworthiness and health care, AI bias becomes a more pressing issue. Developers and data scientists must learn to eliminate discrimination in these models.

Identifying Sources of Bias

The first step in preventing bias in predictive analytics is recognizing where it can come from. The most obvious source is misleading data, like in Amazon’s case, which made it seem like top candidates were most often men. Data from misrepresentative samples or statistics that don’t account for historical nuances will cultivate discrimination in an algorithm as they do in humans.

Developers can unintentionally generate bias in their algorithms by framing questions the wrong way. For example, one health care algorithm showed discrimination against Black patients in determining care as a matter of cost. Focusing on cost trends led it to believe Black people were less in need since they have historically spent less on medical services.

Framing the issue this way fails to account for the years of restricted access to health care that cause these cost-related trends. In this instance, the data itself was not biased, but the way the algorithm analyzed it didn’t account for it.

When developers understand where bias comes from, they can plan to avoid it. They can look for more representative data and ask more inclusive questions to produce fairer results.

Taking an Anti-Bias Approach to Development

As teams start to train a predictive analytics model, they need to take an anti-bias approach. It’s not enough to be unbiased. Instead, developers should consciously look for and address discrimination. Proactive measures will prevent implicit prejudices from going unnoticed.

One of the most critical steps in this process is maintaining diversity among the team. Collaborating with various people can compensate for blind spots that more uniform groups may have. Bringing in employees with diverse backgrounds and experiences can help highlight potentially problematic data sets or outcomes.

In some instances, teams can remove all protected variables like race and gender from data before training the algorithm. Scrubbing to free it of bias before training instead of addressing concerns later can ensure fairer results from the beginning. When demographic information isn’t even a factor, algorithms won’t learn to draw misleading conclusions from it.

Reviewing and Testing Analytics Models

After producing a predictive analytics engine, teams should continue to test and review it before implementation. Technicians and analysts should be skeptical, asking questions whenever something out of the ordinary arises. When an algorithm produces a result, they should ask “why” and look into how it came to that conclusion.

Teams should always test algorithms with dummy data representing real-life situations. The closer these resemble the real world, the easier it will be to spot any potential biases. Using diverse datasets in this process will help reveal a broader spectrum of potential issues.

As mentioned earlier, removing protected variables can help in some instances. In some situations, though, it’s better to use this information to reveal and correct biases. Teams can use their algorithm to measure bias within themselves and then offset it.

Preventing Bias in Predictive Analytics Is a Must

Predictive analytics engines are appearing in an increasing number of applications. As these models play a more central role in decision-making, developers must prevent bias within them. Removing discrimination from predictive analytics can be a challenging task, but it’s a necessary one.
