Course Syllabus

Abstract

The overwhelming majority of courses on data-mining and artificial intelligence implies a strong background in probability and statistics. The goal of this course is to provide those students who are not so keen on the subject matter with its fundamentals.
Learning Objectives

Learning Objectives

  • To introduce the theoretical foundations of Probability theory.
  • To introduce the theoretical foundations of Mathematical statistics.
  • To provide the students with practical skills of modelling real-world in the framework of probability and statistics.
Expected Learning Outcomes
