Synopsis:

Information theory explores the fundamental limits of the representation and transmission of information. We will focus on the definition and implications of (information) entropy, the source coding theorem, and the channel coding theorem. These concepts provide a vital background for researchers in the areas of data compression, signal processing, controls, and pattern recognition.

Requirements:

Basic course of Calculus and Probability (in the extent of the courses 01MAA3, 01MAA4 and 01MIP held at the FNSPE CTU in Prague).

Syllabus of lectures:

1. Information source and entropy, joint and conditional entropy, information divergence, informations and their relation to entropy

2. Jensen inequality and the methods of convex analysis, sufficient statistics and data processing theorem

3. Fano inequality and Cramér-Rao inequality, asymptotic equipartition property of memoryless sources

4. Entropy rates of information sources, stationary and Markov sources

5. Data compression, Kraft inequality for instantaneous and uniquely decodable codes, Huffman codes

6. Capacity of noisy channels, Shannon theorem about transmissibility of a source through a channel

Syllabus of tutorials:
