REGRESSION DETECTION AND CORRECTION IN RELATIONSHIPS BETWEEN PERFORMANCE INDICATORS AND AI METRICS

Abstract:

A computer implemented method for detecting regression in a relationship between a performance indicator and AI metrics includes calculating a baseline threshold of regression degradation according to a historical correlation coefficient corresponding to a performance indicator and a set of AI metrics, calculating a current correlation coefficient according to one or more current data records, identifying a correction constant according to the current correlation coefficient and a desired correlation coefficient, generating a function to predict correction constants corresponding to performance indicator data and the set AI metrics, determining a delta correction constant for each AI metric of the set of AI metrics, applying the determined delta correction constant to the set of AI metrics, and identifying a subset of AI metric outliers according to the calculated baseline threshold and the determined delta correction constant.
