Data set of three species of Penicillium fungi

Description

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.

Usage

Format

This data set contains the following matrices:

X

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.

Y

A matrix of dummy variables for the training data.

Z

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

Details

The X matrix is not normalized.
