Constructor & Destructor Documentation

batch()

batch ( size_t  batchsize, const SAMPLEDLOSSFUNC &  sampledlossfunc, seed_t  seed = default_seed  )

inline

Constructor.

Wrapper around sampled loss functions that only evaluates the loss for a subset of the samples. Each update re-randomizes the subset.

Parameters

batchsize	= size of the batch (same batch size for all packets)
sampedlosfunc	= any sampled loss function (to be subsampled).
