Course objectives

The course introduces students to the fields of Data Mining and Machine Learning, that merge together competencies of statistics and computer science.

The course teaches the differences between tasks and models and introduces the students to some of the popular models in Data Mining such as:

• binary classification and related tasks, 
• tree models, rule models and subgroup discovery
• linear models (least squares, regression),
• Support Vector Machines and Kernel methods.
• Clustering
• Anomaly detection
• Fairness and privacy

The laboratory part of the course introduces the students to python libraries and proposes programming excercises to further develop the understanding of the presented concepts and algorithms.

Results of learning outcomes

As regards “Knowledge and understanding”, the results of the learning outcomes will be mastering some the main concepts in Data Mining and Machine Learning.

As regards “Applying knowledge and understanding”, the students will use the learnt knowledge in the context of modern languages and libraries with the goal to solve some real data science tasks (such as classifying examples into a set of given classes, clustering data into meaningful groups, etc.).

   3. support-vector machines
6. Graph-based Clustering
7. Anomaly detection
   1. clustering based approach
   2. one-class classification
8. Fairness and Privacy

Course delivery

The course lessons will be both theoretical and practical (laboratory sessions)

These classes are divided into 18 theoretical classes and 6 laboratory sessions.

Learning assessment methods

The final exam will be written with an optional oral examination. The written test will assess the understanding of the presented concepts as well as the student ability to solve small practical problems. The written test will be graded up to 27 points out of 30. The optional oral examination will provide extra grade points in the range -27, +5.
