Module contents
Advanced Topics Speech and Audio Processing: After reviewing basic principles of speech processing and statistical signal processing (adaptive filtering), this course covers techniques and underlying algorithms that are essential in many modern-day speech communication and audio processing systems: acoustic echo and feedback cancellation, noise reduction, dereverberation, microphone and loudspeaker array processing, active noise control, time-stretching and pitch-shifting, audio restoration.

Angewandte Psychophysik: Subjective listening experiment design and models of human auditory perception will be treated with a focus on application in sound quality measurement (e.g. for vehicle noise and sound reproduction) and in digital signal processing algorithm development (e.g. for low bit-rate audio coding and headphone virtualizers).

Machine Learning I: 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.
