Eight ways to keep AI bias from creeping into your models

Algorithmic bias in AI is a pervasive problem. These biased algorithm examples frequently appear in the news, such as speech recognition not being able to identify the pronoun “hers” but being able to identify “his”, or face recognition software being less likely to recognize people of color. While eliminating bias in AI is not possible, it’s essential to know not only how to reduce bias in AI, but actively work to prevent it. Knowing how to mitigate bias in AI systems stems from understanding the training data sets that are used to generate and evolve models.

A 2020 State of AI and Machine Learning Report concluded that only 15% of companies reported data diversity, bias reduction, and global scale for their AI as “not important.” While that’s great, only 24% reported unbiased, diverse, global AI as mission critical. This means that numerous AI initiatives still need to make a true commitment to overcoming bias in AI, which is not only indicative of success, but critical in today’s context.

Since AI algorithms are meant to intervene where human biases exist they’re often thought to be unbiased. It’s important to remember that these machine learning models are written by people and trained on socially generated data. This poses the challenge and risk of introducing and amplifying existing human biases into models, preventing AI from truly working for everyone.

Responsible and successful companies must know how to reduce bias in AI, and proactively turn to their training data to do it. To minimize bias, monitor for outliers by applying statistics and data exploration. At a basic level, AI bias is reduced and prevented by comparing and validating different samples of training data for representativeness. Without this bias management, any AI initiative will ultimately fall apart.

 

 

Eight ways to prevent AI bias from creeping into your models:

  1. Define and narrow the business problem you’re solving. Trying to solve for too many scenarios often means you’ll need thousands of labels across an unmanageable number of classes. Narrowly defining a problem, to start, will ensure your model is performing well for the exact reason you’ve built it.
  2. Structure data gathering that allows for different opinions. There are often multiple valid opinions or labels for a single data point. Gathering those opinions and accounting for legitimate, often subjective, disagreements will make your model more flexible
  3. Understand your training data. Both academic and commercial datasets can have classes and labels that introduce bias into your algorithms. The more you understand and own your data, the less likely you are to be surprised by objectionable labels.
  4. Gather a diverse ML team that asks diverse questions. We all bring different experiences and ideas to the workplace. People from diverse backgrounds –race, gender, age, experience, culture, etc. – will inherently ask different questions and interact with your model in different ways. This helps you catch problems before your model is in production.
  5. Think about all your end-users. Likewise, understand that your end-users won’t simply be like you or your team. Be empathetic. Avoid AI bias by learning to anticipate how people who aren’t like you will interact with your technology and what problems might arise in their doing so.
  6. Annotate with diversity. The more spread out the pool of human annotators, the more diverse your viewpoints, which reduces bias both at the initial launch and as you continue to retrain your models.
  7. Test and deploy with feedback in mind. Models are rarely static for their entire lifetime. A common, but major, mistake is deploying your model without a way for end-users to give you feedback on how the model is applying in the real world. Opening a discussion and forum for feedback will continue to ensure your model is maintaining optimal performance levels for everyone.
  8. Have a concrete plan to improve your model with that feedback. You’ll want to continually review your model using not just client feedback, but also independent people auditing for changes, edge cases, instances of bias you might’ve missed, and more. Make sure you get feedback from your model and give it feedback of your own to improve its performance, constantly iterating toward higher accuracy.
