Techniques are described herein for verifying and/or reducing bias in machine learning (ML) models. An ML model may be trained using a baseline training data set (TDS). A second TDS may be generated from the baseline TDS based on executing a classification algorithm to assign each example to one of a set of classes. The class-aware ML models may be trained using class-specific examples (e.g., examples that correspond to a given class). Bias in the ML model may be detected based on providing an input to the ML model and each of the class-aware ML models and identifying differences between their respective outputs. If bias is detected, a parameter that highly correlates to the output of the ML model may be removed from the training data and the process may begin anew. Each iteration of the process may reduce the bias originally detected in the ML model.
