Detailed Description

Common base for all transformations.

Transformations are (usually unsupervised) data preprocessing methods.

Member Function Documentation

virtual Transformer& OpenANN::Transformer::fit ( const Eigen::MatrixXd &  X)

pure virtual

Fit transformation according to training set X.

Parameters

X	each row represents an instance

Returns

this for chaining

Implemented in OpenANN::KMeans, OpenANN::PCA, OpenANN::Compressor, OpenANN::ZCAWhitening, and OpenANN::Normalization.

virtual Transformer& OpenANN::Transformer::fitPartial ( const Eigen::MatrixXd &  X)

inlinevirtual

Fit transformation according to subset of the training set X.

This can be used for online adaption of the transformation.

Parameters

X	each row represents an instance

Returns

this for chaining

Reimplemented in OpenANN::Compressor.

virtual Eigen::MatrixXd OpenANN::Transformer::transform ( const Eigen::MatrixXd &  X)

pure virtual

Transform the data.

Parameters

X	each row represents an instance

Returns

transformed data

Implemented in OpenANN::KMeans, OpenANN::PCA, OpenANN::Compressor, OpenANN::ZCAWhitening, and OpenANN::Normalization.
