HotPLS is a free MATLAB toolbox accompanying the recently published article “Hierarchically ordered taxonomic classification by partial least squares” in Chemometrics and Intelligent Laboratory Systems. It consists of an example script, the same data set found in the article and all necessary functions to perform the calculations in the article.
The included set of functions can be used in any situation where classification is performed in a fixed hierarchy and where the data are multivariate, e.g. spectroscopic measurements or similar.
For a thorough description of the method and example see:
Kristian Hovde Liland, Achim Kohler, Volha Shapaval, Hot PLS—a framework for hierarchically ordered taxonomic classification by partial least squares. Chemometrics and Intelligent Laboratory Systems, Volume 138, 15 November 2014, Pages 41–47.
