Bayesian model selection and multimodeling
Course page: https://github.com/Intelligent-Systems-Phystech/BMM-21
The lecture course delivers the main problem of machine learning, the problem of model selection. One can set a heuristic model and optimise its parameters, or select a model from a class, or make a teacher model to transform its knowledge to a student model, or even make an ensemble from a models. Behind all these strategies there is a fundamental technique: the Bayesian inference. It assumes hypotheses about the measured data set, about the model parameters and even about the model structure. And it deduce the error function to optimise. This is called the Minimum Description Length principle. It selects simple, stable and precise models. This course joins the theory and the practical lab works of the model selection and multimodeling.
