C# Class Microsoft.MSR.CNTK.Extensibility.Managed.CSEvalClient.ModelEvaluator

This class provides an Eval model wrapper to restrict model evaluation calls to one at a time.

This class is not thread-safe except through the static methods. Each ModelEvaluator instance wraps an Eval model, and exposes the Evaluate method for either a vector of inputs or a record string. The static interface provides the management of the concurrency of the models and restricts the evaluations to a single thread.

Public Methods

Method	Description
DisposeAll ( ) : void	Disposes of all models
Evaluate ( List inputs ) : List	Evaluated a vector and returns the output vector
Evaluate ( string record ) : bool	Evaluates a record containing the input data and the expected outcome value
Initialize ( int numConcurrentModels, string modelFilePath, int numThreads = 1 ) : void	Initializes the Model Evaluator to process multiple models concurrently

Private Methods

Method	Description
Dispose ( ) : void	Disposes of the resources
EvaluateInput ( List inputs ) : List	Evaluates an input vector against the model as the first defined input layer, and returns the first defined output layer
EvaluateRecord ( string record ) : bool	Evaluates a test record
ModelEvaluator ( string modelFilePath, int numThreads, int id ) : System	Creates an instance of the ModelEvaluator class. The id is used only for debugging purposes
