Root Cause

Loss function doesnt match model output activation.

generic

Workarounds

  1. 92% success Match: sigmoid+binary_crossentropy or softmax+categorical_crossentropy
  2. 90% success Use from_logits=True to let loss function handle activation

Dead Ends

Common approaches that don't work:

  1. Use MSE for all classification tasks 82% fail

    Wrong loss for classification

  2. Add sigmoid then use binary_crossentropy 78% fail

    Double sigmoid problem
