Change Log

Major changes and updates since the v1.6.0 release:

Training Support, as a tech preview

  • A set of new training features are introduced to represent neural network models in the process of model training.
  • A protobuf message TrainingInfoProto is added to store training information, including the algorithm and initializers, as well as new operators Gradient and GraphCall and new functions describing most commonly used Loss functions and Optimizers, all in the domain
  • The new spec allows one to create a model training task or a partially trained model in one framework, then export it in ONNX and load into a runtime or another framework where the training can proceed, with the expectation of theoretically similar outcome to the model trained in the original framework.
  • Note the converters do not support training yet. The goal of this tech preview is to test the new spec and to enable converters to add full support in future releases.
