pLSA – Probabilistic Latent Semantic Analysis of Imaging Mass Spectrometry Data

pLSA

:: DESCRIPTION

pLSA contains MATLAB code to perform a probabilistic Latent Semantic Analysis of Imaging Mass Spectrometry Data. In contrast to other unsupervised methods like Principal Component Analysis or Independent Component Analysis this method accounts for the non-negativity of mass spectra.
