Detailed Description

Infomax ICA.

Given an observation matrix and input parameters, return the corresponding unmixming matrix, W. Exmaple use:

   InfomaxICA *ica = new InfomaxICA(lambda, B, epsilon);
   Matrix west;
   ica->applyICA(dataset);  
   ica->getUnmixing(west);

Member Function Documentation

void InfomaxICA::applyICA

(

const Matrix &

dataset

)

Sphere the data, apply ica.

This is the first function to call after initializing the variables.

Definition at line 61 of file infomax_ica.cc.

References GenMatrix< T >::Copy(), and evaluateICA().

void InfomaxICA::displayMatrix

(

const Matrix &

m

)

Simple display matrix function.

Definition at line 274 of file infomax_ica.cc.

void InfomaxICA::displayVector

(

const Vector &

m

)

Simple display vector function.

Definition at line 287 of file infomax_ica.cc.

References GenVector< T >::length().

void InfomaxICA::evaluateICA

(

)

Run infomax.

Call this after initialization and applyICA.

Definition at line 85 of file infomax_ica.cc.

References linalg__private::AddTo(), and linalg__private::Scale().

Referenced by applyICA().

void InfomaxICA::getSources	(	const Matrix &	dataset,
		Matrix &	s
	)

Return the source estimates, S.

S is a reference to an uninitialized matrix.

Definition at line 307 of file infomax_ica.cc.

void InfomaxICA::getUnmixing

(

Matrix &

w

)

Return the current unmixing matrix estimate.

Requires a reference to an uninitialized matrix.
