Detailed Description

This is an abstract class which declares some methods to be implemented by a iomanager. To use your own input procedures you must write a derived class of iomanage that implements the two methods, info_from_file and load_patterns.

The class implements two static methods to allocate and destroy input and output vectors. Method allocate_data can be used to call allocate_data and load_patterns (virtually binded to the derived class method).

One example of a derived class is iomanagelwnnfann.

Member Function Documentation

virtual void iomanage::info_from_file (  const string &  filename, int *  npatterns, int *  ninput, int *  noutput )  [pure 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. Implemented in iomanagebinary, and iomanagelwnnfann.

virtual void iomanage::load_patterns (  const string &  filename, float **  inputs, float **  targets, int  ninput, int  noutput, int  npatterns )  [pure 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). You can use allocate_data() to allocate the memory. If the number of inputs or outputs of the patterns in the file is not equal to ninput and noutput throws a runtime_error. Can throw a runtime_error exception if the format of the file isn't right. Implemented in iomanagebinary, and iomanagelwnnfann.

void iomanage::allocate_data (  int  npattern, int  ninput, int  noutput, float **&  input, float **&  target )  [static]

Allocate data for patterns. Parameters: npattern  number of patterns ninput  number of inputs noutput  number of outputs input  vector of inputs (not allocated) target  vector of targets (not allocated)

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

Allocate memory and load data from a 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  Return Number of inputs. noutput  Return Number of outputs npatterns  Return Number of patterns

void iomanage::destroy (  int  npatterns, float **  input, float **  output )  [static]

free memory for input and output Parameters: npatterns  Number of patterns input  Input vector to be freed output  Output vector to be freed
