What is AI bias?

I bias refers to systematic and repeatable errors in a computer system that create unfair outcomes, such as privileging one arbitrary group of users over others. This bias in AI systems typically stems from various sources:

Data Bias: This occurs when the training data used to train AI models is not representative of the broader population or reality it is intended to model. The data might overrepresent or underrepresent certain groups, leading to decisions that are biased towards the majority group present in the training set.

Algorithmic Bias: Sometimes, the algorithms themselves can introduce bias if they are designed in a way that inherently favors certain outcomes. This can happen due to the assumptions made during the algorithm’s development or through the selection of models that are not appropriate for the task.

Prejudice Bias: This type of bias is introduced when the data or the labels used in training contain prejudiced perspectives. For example, if historical data reflects past prejudices, the AI system will likely learn to replicate those biases.

Measurement Bias: This arises when the tools or methods used to collect data are flawed. For example, a facial recognition technology that fails to accurately identify individuals from certain racial backgrounds due to the limitations in the technology used to measure and collect image data.

Evaluation Bias: When the metrics used to evaluate an AI system do not adequately measure fairness or accuracy across different groups, evaluation bias can occur. This might lead an AI system to be tuned in a way that overlooks its poor performance for certain demographics.

Addressing AI bias involves several strategies, such as diversifying training data, developing algorithms with fairness in mind, regularly testing AI systems for biases, and involving a diverse group of people in the design and development process to ensure multiple perspectives are considered. Additionally, regulatory and ethical guidelines are increasingly being developed and implemented to help mitigate the risks of AI bias.
