Course syllabus: Bayesian model selection and multimodeling

The lecture course delivers the main problem of machine learning, the problem of model selection. One can set a heuristic model and optimize its parameters, select a model from a class, make a teacher model to transform its knowledge into a student model, or even make an ensemble from models. Behind all these strategies is a fundamental technique: the Bayesian inference. It assumes hypotheses about the measured data set, the model parameters, and even about the model structure. And it deduces the error function to optimize. 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 model selection and multimodeling. https://github.com/Intelligent-Systems-Phystech/BMM-21 Course page]
