szha commented on issue #5559: CTC Loss Refactor URL: https://github.com/apache/incubator-mxnet/issues/5559#issuecomment-327702925 @buaacszj the change I mentioned above is based on @sbodenstein's work on contrib CTC and my changes are mainly in improving usability, such as to remove the effect of undefined gradients inside padding area, and improve numerical stability by doing log softmax for the log probabilities. I haven't done thorough analysis on its speed. Do you have ideas on how it can be improved? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
