Functions
double	DoBackpropParallel (const Nnet &nnet, int32 minibatch_size, SequentialNnetExampleReader *example_reader, double *tot_weight, Nnet *nnet_to_update)
	This function is similar to "DoBackprop" in nnet-update.h This function computes the objective function and either updates the model or computes parameter gradients. More...
double	DoBackpropSingleThreaded (const Nnet &nnet, int32 minibatch_size, const std::vector< NnetExample > &egs, double *tot_weight, Nnet *nnet_to_update)
double	DoBackpropParallel (const Nnet &nnet, int32 minibatch_size, int32 num_threads, const std::vector< NnetExample > &examples, double *num_frames, Nnet *nnet_to_update)
	This version of DoBackpropParallel takes a vector of examples, and will typically be used to compute the exact gradient. More...
