Documentation

This machine implements the Parzen Window estimator. Given a dataset (in the constructor), the forward method returns for a given input the average of the outputs of the training set weighted by a Gaussian kernel distance:

The only parameter var is given in the constructor.

real var

the variance used

DataSet* data

The dataset that contains the training set

int* real_examples

the indices of the training examples

real denominator

keep the denominator

int n_outputs

the size of the output vector

int n_inputs

the size of the input vector

ParzenMachine(int n_inputs_, int n_outputs_, real var_)

virtual void setVar(real var_)

change the value of var

This class has no child classes.
