Probabilistic Archetypal Analysis

Scripts for probabilistic archetypal analysis (Seth and Eugster, 2013).

MATLAB scripts to reproduce figures:

• Demo (MATLAB script)
• Classic AA on binary data (MATLAB script)
• Classic AA on Poisson data (MATLAB script)
• Classic AA on multinomial data (MATLAB script)
• Convergence (MATLAB script)
• Negative log-likelihood (MATLAB script)

R scripts to reproduce applications:

• Normal observations: Archetypal soccer players (R script)
• Multinomial observations: NIPS bag-of-words (R script)
• Bernoulli observations: Austrian national guest survey (R script)
• AA versus PAA (R script)
• Poisson observations: Disasters worldwide from 1900-2008 (R script)
  • AA versus PAA (R script)
