  • Patent number: 11734612
    Abstract: In various embodiments, a process for obtaining a generated dataset with a predetermined bias for evaluating algorithmic fairness of a machine learning model includes receiving an input dataset and generating an anonymized reconstructed dataset based at least on the input dataset. The process includes introducing a predetermined bias into the generated dataset, forming an evaluation dataset based at least on the generated dataset with the predetermined bias, and outputting the evaluation dataset. In various embodiments, a process for training a generative model includes configuring a generative model and receiving training data, where the training data includes a tabular dataset. The process includes using computer processor(s) and the received training data to train the generative model, where the generative model is sampled to generate a dataset with a predetermined bias.

  • Publication number: 20220027679
    Abstract: A data stream is received. Data elements of the data stream are analyzed using one or more machine learning models and one or more machine learning prediction explanation implementations. Different candidate presentations are tested. The different candidate presentations are associated with machine learning results provided to different reviewers in a group of human-in-the-loop reviewers that review predictions of the one or more machine learning models. The different candidate presentations include different explanations generated by the one or more machine learning prediction explanation implementations and at least one control candidate presentation corresponding to an absent explanation. Different aspects of the testing are monitored. Results of the monitoring are used to make a selection among the different candidate presentations.
