Detailed Description

Data class that contains a model's large data, purely in system memory.

Author: Daniel Wirtz

Date: 2011-08-03

New in 0.5:: (Daniel Wirtz, 2011-08-03) Added this class (new organization for model data).

Change in 0.3:: (Syed Ammar, 2011-05-10) Implemented setters for the properties

Change in 0.3:

(Daniel Wirtz, 2011-04-01)

Changed the old ProjTrainData to TrainingData, as this property name describes the usage more precisely.

Change in 0.1:: (Daniel Wirtz, undated) More common projection via matrices \(V,W\) instead of \(V,V^t\).

This class is part of the framework
