Code Refactoring

  • model: remove episode long RNN state tracking (11095ab)

  • a3c: add bahdanau attention layer (daba776)

BREAKING CHANGES

  • this removes a model feature that makes previous pretrained models incompatible
  • model: this removes long-term RNN state tracking across episodes. Tracking the state was a significant amount of code and it wasn't clear that it made the model substantially better at any given task.

The overhead associated with keeping lots of hidden states in memory and calculating state histories was not insignificant on CPU training setups as well.
