penicilliumYES: Data set of three species of Penicillium fungi

Description Usage Format Details Source References


The data set penicilliumYES has 36 rows and 3754 columns. The variables are 1st order statistics from multi-spectral images of three species of Penicillium fungi: Melanoconidium, Polonicum, and Venetum. These are the data used in the Clemmemsen et al "Sparse Discriminant Analysis" paper.




This data set contains the following matrices:


A matrix with 36 columns and 3754 rows. The training and test data. The first 12 rows are P. Melanoconidium species, rows 13-24 are P. Polonicum species, and the last 12 rows are P. Venetum species. The samples are ordered so that each pair of three is from the same isolate.


A matrix of dummy variables for the training data.


Z matrix of probabilities for the subcalsses of the training data.


The X matrix is not normalized.
