### Course Syllabus

#### Abstract

This course introduces the basic theoretical and applied principles of Bayesian statistical analysis in a manner geared toward students in the social sciences. The Bayesian paradigm is particularly useful for the type of data that social scientists encounter given its recognition of the mobility of population parameters, its ability to incorporate information from prior research, and its ability to update estimates as new data are observed. The course consists of three main sections: a Bayesian approach to probability theory, sampling methods, and major types of generative models.

#### Learning Objectives

• Mastering the Bayesian approach to probability theory and the main ways to apply it to machine learning problems
• Acquisition of skills in building probabilistic models, deriving the necessary formulae for solving learning and inference problems within the framework of the built probabilistic models, as well as effective implementation of these models on the computer

#### Expected Learning Outcomes

• Know the main Bayesian models used to solve various machine learning problems (mixture distributions, Relevant Vector Model, etc.)
• Know the basic methods of generating a sample from a non-normalised probability distribution
• Know the basic methods of learning and inference in probabilistic models (exact and approximate)
• Know how to choose the appropriate learning method for the given models
• Know how to derive the necessary formulas for solving learning and inference problems within the framework of constructed probabilistic models
• Be able to build probabilistic models that take into account the structure of the applied machine learning problem
• Be able to efficiently implement these models on a computer

#### Course Contents

• A Bayesian approach to probability theory. Full Bayesian inference
