Latent Variable Models

For ecology and biology

You will find here the material I use for my Latent Variables Models for ecology and biology Class in Master 2 Mathématiques pour les Sciences du Vivant of University Paris Saclay.

Slides of the course

• Chap 1 : Introduction

• Chap 2 : mixture models

• ZI-Poisson TP: Data and instructions

• Chap 3 : Hidden Markov Models

• Chap 4 : Stochastic Block Models . This class will be completed by a tutorial on R.

• Chap5 : A gentle introduction to Variational probabilistic Autoencoder

• Chap 6 : Bayesien inference of Latent variable models.

  • Slides are here .
  • Some R code examples are given here.
    
  • In particular, we will study the difference between Variational inference and MCMC on the Poisson Mixture model. The codes are here.
