Restricted Boltzmann Machines as Models of Interacting Variables

no code implementations29 Mar 2021 Nicola Bulso, Yasser Roudi

We study the properties of these interactions in detail and evaluate how the accuracy with which the RBM approximates distributions over binary variables depends on the hidden node activation function and on the number of hidden nodes.

On the complexity of logistic regression models

no code implementations1 Mar 2019 Nicola Bulso, Matteo Marsili, Yasser Roudi

We investigate the complexity of logistic regression models which is defined by counting the number of indistinguishable distributions that the model can represent (Balasubramanian, 1997).

Model Selection regression

Sparse model selection in the highly under-sampled regime

no code implementations3 Mar 2016 Nicola Bulso, Matteo Marsili, Yasser Roudi

We propose a method for recovering the structure of a sparse undirected graphical model when very few samples are available.
