392123 Introduction to Data Mining (V) (WiSe 2025/2026)

The course covers foundational methods of data mining, explorative data analysis, and visualization. The focus is on educational data (so-called 'educational data mining' or 'learning analytics'). Example methods are:

• statistical tests, esp. t-tests and signed rank test
• Principal Component Analysis
• k-Means Clustering
• Item Response Theory
• Bayesian Knowledge Tracing
• Variational Auto Encoders
• Generative Models

The core skills taught are:

• critical, analytical thinking about models and applications of data mining
• how to design models (formalization, following modeling arguments)
• how to implement models (in Python)
• debugging and interpreting models when applied to data
