Detailed Description

Class for reading and writing binary patterns file.

This class extends iomanage and implements the reading from a binary file The method write_patterns make easy to write a binary pattern file and to convert any training set in this format

Member Function Documentation

virtual void iomanagebinary::info_from_file (  const string &  filename, int *  npatterns, int *  ninput, int *  noutput )  [virtual]

Read info from file. Parameters: filename  the name of a file of input/output pairs npatterns  Pointer to a int where is returned the number of pairs in the file ninput  Pointer to a int where is returned the number of inputs noutput  Pointer to a int where is returned the number of outputs Can throw a runtime_error exception if file does not exist. Implements iomanage.

virtual void iomanagebinary::load_patterns (  const string &  filename, float **  inputs, float **  targets, int  ninput, int  noutput, int  npatterns )  [virtual]

Read patterns from file. Parameters: filename  the name of a file of input/output pairs inputs  Read the inputs in this matrix targets  Reat the targets in this matrix ninput  Number of inputs wanted. noutput  Number of outputs wanted npatterns  Number of patterns wanted Precondition: memory in inputs and outputs has been allocated for npatterns with ninput and noutput vectors. (First index is the index of pattern, second index is the index of neuron) If the number of inputs or outputs of the patterns or the number of patterns in the file is not equal to ninput and noutput and npatterns throws a runtime_error. Can throw a runtime_error exception if the format of the file isn't right. Implements iomanage.

void iomanagebinary::write_patterns (  const string &  filename, float **  inputs, float **  targets, int  ninput, int  noutput, int  npatterns )

Write patterns to a binary file file. Parameters: filename  the name of the file to be written inputs  Read the inputs in this matrix targets  Reat the targets in this matrix ninput  Number of inputs. noutput  Number of outputs npatterns  Number of patterns Can throw a runtime_error exception if file is not writeable.

void iomanagebinary::convert (  const string &  sourceformatfn, const string &  binformatfn, iomanage *  sourceFormatIomanager )

Convert patterns from any format to binary format. Parameters: sourceformatfn  filename containing patterns in original format binformatfn  filename to be written in binary format sourceFormatIomanager  iomanager managing file in original format
