Courses

Course Offering

We offer two seminars "Probabilistic Modeling I (Inf 533) / II (534)"

Seminar Probabilistic Modeling I (Inf 533) / II (Inf 534)

The seminar consists of two parts, which take place in the winter semester (Part I) and in the summer semester (Part II).
In Part I we will deal with the state-of-the-art (SoA) in probabilistic modeling using probabilistic programming languages (as an example the DSL WebPPL) in cognition (perception, problem solving, evaluation, decision making) and behavioral control of predominantly natural agents.
Part II deals with probabilistic modeling in technical, epidemiological and ecological contexts.We will also consider the SoA in the development of new probabilistic modeling languages (e.g. PyRo, TURING, Greta, PyMC3).
This division of the contents adapts to the students' previous knowledge and wishes.
The successful participation in both seminars can be combined in such a way that it corresponds to a lecture module.

 

 

Transpilation of SICP into Julia/Pluto.jl

Learning Julia/Pluto.jl by Climbing the SICP-Mountain

"Structure and Interpretation of Computer Programs (SICP) is a computer science textbook by Massachusetts Institute of Technology professors Harold Abelson and Gerald Jay Sussman with Julie Sussman. It is known as the Wizard Book in hacker culture.[1][2] It teaches fundamental principles of computer programming, including recursion, abstraction, modularity, and programming language  design and implementation." (Wikipedia, 2021/09/15)

SICP-scripts are written in MIT-SCHEME invented in the 90ies at the MIT AI Lab. Scheme is a minimalist dialect of the Lisp family of programming languages. JULIA was also but nearly 30 years later invented at the very same MIT. This happened 2009 not at the MIT AI Lab but at MIT's Computer Science and AI Laboratory (CSAIL). Here we present transpilations into JULIA within a Pluto.jl-embedding.
