Description
This PR:
contrast_utilsmodule.is_attributed_fnbool flag (default:False) to theStepFunctionBaseArgsclass. This flag enables custom behavior during step function execution by checking whether the function is being called as a step function or as an attribution target.contrast_prob_diffas an attributed function (Bug about 'contrast_prob_diff' #188) by forcing original inputs at every step whenperforming contrastive feature attribution (matching Yin and Neubig (2022) implementation). The previous behavior allowing for measuring contrastive probability difference in presence of different input sources is preserved when the function is used as step function.
