func_test: Test Function Model

In Microsoft/CNTK-R: R Interface to the Microsoft Cognitive Toolkit (CNTK)

Description

Measures the performance of a model, given by its criterion function, in the form of average metric value (or loss if model has only one output) on a set of data.

Usage

func_test(func, minibatch_source, minibatch_size = 32, streams = NULL,
  model_inputs_to_streams = NULL, callbacks = NULL)

Arguments

func	- The CNTK 'Function' instance on which to apply the operation
minibatch_source	- minibatch source for the test data
minibatch_size	(minibatch_size_schedule or int) – minibatch size for evaluation
streams	(list) - the streams of the minibatch_source in argument order
model_inputs_to_streams	(dict or named list) - mapping between input variables and #' input streams
callbacks	(progress writer or list of them) – optionally, list of progress writers from cntk.logging to automatically track training progress.
