For the displayed correct response, local A_t^(0) gives sparse supervision and noticeable negative credit to only a few tokens, whereas normalized A_t^(0.99) propagates later information, smooths the signal, assigns stronger positive credit to the key mathematical derivation, and mildly penalizes redundant text. · CiteArk
