Detailed Description

Responsible for loading data sets from file or generating random data to use.

Constructor & Destructor Documentation

DataLoader::DataLoader ( QObject *  parent = 0 )

explicit

Default Qt-style constructor.

Initializes the random seed for RandomData

Member Function Documentation

bool DataLoader::LoadData	(	const QString &	path,
		DataSet &	dataset
	)		const

Loads a data set from the specified file path.

The file format is basically a CSV, with tuples of (label,data) entries. Each row is an element of the time series (usually month, etc). The first line of the file has to be the string #STACKED

Parameters

path	The path to the data file
dataset	the DataSet to load into

Returns

true if loading succeeded, false on error

void DataLoader::RandomData	(	int	numItems,
		DataSet &	dataset
	)		const

Generates a random dataset of numItems layers.

It will have a time series of length 12. The dataset is created by randomly placing some gaussian curves on each layer.

Parameters

numItems	the number of layers to create
dataset	the DataSet to write into
