Constructor & Destructor Documentation

reranker::EndOfEpochModelWriter::EndOfEpochModelWriter ( const string &  model_file, shared_ptr< ModelProtoWriter >  writer, bool  compressed, bool  use_base64, bool  verbose = true  )

inline

Constructs a new instance to write out the best model to the specified file.

A model will only be serialized if the best model epoch so far is different from that of the last model written out by this hook.

Parameters

model_file	the name of the file to which to serialize a Model
writer	the serializer for serializing a Model to a ModelMessage
compressed	whether to use compression when serializing a Model
use_base64	whether to serialize using base64 encoding
verbose	whether this end-of-epoch hook should be verbose

Member Function Documentation

virtual void reranker::EndOfEpochModelWriter::Do ( Model *  model )

inlinevirtual

Executes this end-of-epoch hook, which writes out the best model so far if its epoch differs from that of the last model written out by this hook.

For safety, the model will be first serialized to a temporary file and then moved into place.

Parameters

model

the model that will execute this hook in its Model::EndOfEpoch method

See Also

Model::set_end_of_epoch_hook

Implements reranker::Model::Hook.
