Wednesday: 12:15  13:45, weekly (from 19/10/22), Location: W03 1156 Dates on Wednesday, 22.02.2023 15:00  19:00, Location: W03 1161
The field of Machine Learning develops and provides methods for the analysis of data and signals. Typical application domains are computer hearing, computer vision, general pattern recognition and largescale data analysis (recently often termed "Big Data"). Furthermore, Machine Learning methods serve as models for information processing and learning in humans and animals, and are often considered as part of artificial intelligence approaches.
This course gives an introduction to unsupervised learning methods, i.e., methods that extract knowledge from data without the requirement of explicit knowledge about individual data points. We will introduce a common probabilistic framework for learning and a methodology to derive learning algorithms for different types of tasks. Examples that are derived are algorithms for clustering, classification, component extraction, feature learning, blind source separation and dimensionality reduction. Relations to neural network models and learning in biological systems will be discussed were appropriate.
The course requires some programming skills, preferably in Matlab or Python. Further requirements are typical mathematical / analytical skills that are taught as part of Bachelor degrees in Physics, Mathematics, Statistics, Computer and Engineering Sciences. Course assignments will include analytical tasks and programming task which can be worked out in small groups.
The presented approach to unsupervised learning relies on Bayes' theorem and is therefore sometimes referred to as a Bayesian approach. It has many interesting relations to physics (e.g., statistical physics), statistics and mathematics (analysis, probability theory, stochastic) but the course's content will be developed independently of detailed prior knowledge in these fields.

5.04.4571  Densityfunctional theory
 Prof. Dr. Caterina Cocchi
Wednesday: 14:15  15:45, weekly (from 19/10/22) Friday: 08:15  09:45, weekly (from 21/10/22)
Description: The objective of this class is to introduce students to ab initio methods for electronicstructure calculations based on densityfunctional theory (DFT). The topics will be approached from the viewpoint of condensedmatter physics. In the first part of the semester, theoretical lectures will be accompanied by exercise sessions. The last few weeks of the term will be exclusively dedicated to handon tutorials. At the end of this course, participants are expected to be familiar with the theoretical foundation of DFT, to be able to perform a DFT calculation with good control of the given approximations, and to know how to interpret the outcoming results.
The course as a whole (theoretical lectures, exercises, and handson tutorials) can be offered in presence, in digital form, or even in a mixed regime, depending on the circumstances and on the students’ needs.
The course is addressed to Master’s students in theoretical physics. However, Master’s students in experimental physics, doctoral students in all specializations, and Bachelor’s students who are interested in (computational) electronicstructure theory are very welcome to participate. Good knowledge of quantum mechanics is the only prerequisite to attend this class.
