Researchers Reduce Bias in aI Models while Maintaining Or Improving Accuracy
Brigitte Cammack hat diese Seite bearbeitet vor 7 Monaten
Machine-learning models can fail when they try to make forecasts for people who were underrepresented in the datasets they were trained on.
For example, a design that forecasts the very best treatment choice for somebody with a chronic disease might be trained utilizing a dataset that contains mainly male clients. That model may make incorrect predictions for female clients when released in a medical facility.
To enhance results, engineers can try balancing the training dataset by eliminating data points till all subgroups are represented similarly. While dataset balancing is appealing, it frequently needs eliminating large amount of data, harming the design’s overall performance.
MIT a brand-new strategy that recognizes and removes particular points in a training dataset that contribute most to a design’s failures on minority subgroups. By getting rid of far less datapoints than other approaches, this technique maintains the overall accuracy of the design while improving its efficiency relating to underrepresented groups.
