Detailed Description

"Pami Toy" problem for binary classification, as used in the article "Glasmachers and C. Igel. Maximum Likelihood Model Selection for 1-Norm Soft Margin SVMs with Multiple Parameters. IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010." In summary, the first M dimensions are correlated to the labels, the last N dimensions are not.
