The 2022/23 course “Bayesian Machine Learning and Information Processing” will start in November 2022 (Q2).
This course provides an introduction to Bayesian machine learning and information processing systems. The Bayesian approach affords a unified and consistent treatment of many useful information processing systems.
This course covers the fundamentals of a Bayesian (i.e., probabilistic) approach to machine learning and information processing systems. The Bayesian approach allows for a unified and consistent treatment of many model-based machine learning techniques. Initially, we focus on Linear Gaussian systems and will discuss many useful models and applications, including common regression and classification methods, Gaussian mixture models, hidden Markov models and Kalman filters. We will discuss important algorithms for parameter estimation in these models including the Expectation-Maximization (EM) algorithm and Variational Bayes (VB). The Bayesian method also provides tools for comparing the performance of different information processing systems by means of estimating the Bayesian evidence for each model. We will discuss several methods for approximating Bayesian evidence. Next, we will discuss intelligent agents that learn purposeful behavior from interactions with their environment. These agents are used for applications such as self-driving cars or interactive design of virtual and augmented realities. Indeed, in this course we relate synthetic Bayesian intelligent agents to natural intelligent agents such as the brain. You will be challenged to code Bayesian machine learning algorithms yourself and apply them to practical information processing problems.

- Dr. Wouter Kouw (email@example.com) teaches all practical sessions on probabilistic programming with label W.
- Magnus Koudahl, Tim Nisslbeck, Sepideh Adamiat and Wouter Nuijten are the teaching assistants. Mr. Koudahl presents the “What is Life?” bonus lecture.
In principle, you can download all needed materials from the links below.
Please consider downloading the following books/resources:
- Bert de Vries (2022), PDF bundle of all lecture notes for lessons B0 through B12.
- Wouter Kouw (2022), PDF bundle of all probabilistic programming lecture notes for lessons W1 through W4.
- Christopher M. Bishop (2006), Pattern Recognition and Machine Learning. You can also buy a hardcopy, e.g. at bol.com.
- Ariel Caticha (2012), Entropic Inference and the Foundations of Physics.
- We will provide a web-based environment with all necessary software pre-installed and tested, which will allow you to execute code in the lesson notebooks and work on your probabilistic programming assignment. The invitation link will be posted on Piazza.
- If you prefer working on your own machine, we recommend installing Microsoft’s VS Code editor (download) and adding the Jupyter (tutorial) and Julia (tutorial) extensions. Note that we will not support you in installing these tools on your own machine.
