Abstract
A new approach is proposed to support two variants of the approach to effectively generate reason codes for an ensemble model. Both variants involve treating the ensemble model as a black box, identifying trivial values for input variables to the ensemble model, replacing each of the input variables to the ensemble model with its corresponding trivial values and then evaluating the impact on a score of the model after the trivial value replacement. The evaluation result of the impact is then used to generate the reason codes for the ensemble model. Specifically, the first variant is configured to perform one round of replacement, wherein variables with top drops in the score will be the reason codes. The second variant is configured to perform multiple rounds of replacement, which in each round, keeps the identified reason codes variables replaced with trivial values and analyzes incremental drops of replacing remaining variables.
