  • 06-2bHave you mitigated the impact of features that may create bias?
    • Selecting data attributes to train the AI model can not only allow efficient training but also reduce computational resources and costs. An in-depth understanding of data in the relationship analysis between various attributes can help identify potential biases.

    • Simple approaches to mitigate bias include feature selection which excludes features that may lead to bias. The three methods for feature selection are filter, wrapper, and embedded methods. These methods analyze the statistical correlation of features in the data to use features with high correlation coefficients or use subsets with great performance on certain features.

    • The methods, however, are not always effective, as they can reinforce or create different types of bias when removing features associated with bias. Therefore, you must consider various techniques (e.g. reweighting, relabeling, latent variable, sampling) to mitigate bias.

    • But there can be exceptions if you can mitigate bias during the training or if bias was intentional based on the AI system’s purpose.
