Using Bayesian Statistics for variable selection in Machine Learning modelling

In this project, the goal was to find a way to rank models within a subset of a database's variables. Sometimes, we have too many variables, so we are interested in finding a subset which could be give better results than using the whole dataset, in addition to lowering the number of calculations by having less variables. The number of models being , it becomes quite impossible to calculate a criterion for every one of them, especially with a lot of variables.

We explain how to use a MCMC algorithm that searches for these good models. We get very satisfying results despite having like in our paper's example. That corresponds to 5.5e216 models possible, and yet in a reasonable amount of time our algorithm finds very satisfying possible models.
