Detailed Description

SparseGridMinerSplittingTwoDatasets models a datamining process that involves two input datasets that are first split into validation and training data.

The model is then trained on the training data for several epochs.

Constructor & Destructor Documentation

SparseGridMinerSplittingTwoDatasets() [1/3]

sgpp::datadriven::SparseGridMinerSplittingTwoDatasets::SparseGridMinerSplittingTwoDatasets	(	std::vector< DataSourceSplitting * >	dataSource,
		ModelFittingBase *	fitter,
		Scorer *	scorer,
		Visualizer *	visualizer
	)

Constructor.

Parameters

dataSource	vector of configured instances of data source object, that will provide samples to learn from. The miner instance will take ownership of the passed object.
fitter	configured instance of fitter object that generalize the model. The miner instance will take ownership of the passed object.
scorer	configured instance of scorer object that will assess the quality of the generalization provided by the fitter on testing data. The miner instance will take ownership of the passed object.
visualizer	configured instance of viusalizer object that will produce the output to visualize the model and its results

double sgpp::datadriven::SparseGridMinerSplittingTwoDatasets::learn ( bool  verbose )

overridevirtual

Perform Learning cycle: Get samples from data source and based on the scoring procedure, generalize data by fitting and asses quality of the fit.

The learning process first divides the data into training and validation data and trains the model for several epochs on the training data.
