# 190.012 Introduction to Machine Learning (2SH L, SS)

This course is based on the* Machine Learning book* by Univ.-Prof. Dr. Elmar Rueckert.

It is written for experienced undergraduates or for first

semester graduate students.

The lecture provides the basic knowledge for the application of modern machine learning methods. It includes an introduction to the basics of data modeling and probability theory. Classical probabilistic linear and non-linear regression methods are derived and discussed using practical examples.

## Course Topics

- Introduction to Machine Learning (Data and modelling fundamentals)
- Introduction to Probability Theory (Statistics refresher, Bayes Theorem, Common Probability distributions, Gaussian Calculus).
- Linear Probabilistic Regression (Linear models, Maximum Likelihood, Bayes & Logistic Regression).
- Nonlinear Probabilistic Regression (Radial basis function networks, Gaussian Processes, Recent research results in Robotic Movement Primitives, Hierarchical Bayesian & Mixture Models).

## Learning objectives / qualifications

- Students get a comprehensive understanding of basic probability theory concepts and methods.
- Students learn to analyze the challenges in a task and to identify promising machine learning approaches.
- Students will understand the difference between deterministic and probabilistic algorithms and can define underlying assumptions and requirements.
- Students understand and can apply advanced regression, inference and optimization techniques to real world problems.
- Students know how to analyze the models’ results, improve the model parameters and can interpret the model predictions and their relevance.
- Students understand how the basic concepts are used in current state-of-the-art research in robot movement primitive learning and in neural planning.

## Grading

The course will be graded based on a **written exam** (100 Points). 50% of all questions need to be answered correctly to be positive. The exam will take place in the classroom, or **online,** depending on the current university regulations.

In addition, up to **10 bonus points** obtained in regular quiz sessions in the classroom, and **20% of the achieved points** of the Machine Learning Lab will be added to your exam result. Note that bonus points can only be obtained when attending the lectures in person.

**Grading scheme:** 0-49.9Pts (5), 50-65.9Pts (4), 66-79Pts (3), 80-91Pts (2), 92-100Pts (1).
