Course Title: IEG 5154 Information Theory

Description: The course aims to cover

 

  1. Fundamental definitions of information measure (entropy, conditional entropy, mutual information) and their properties.
  2. Lossless Source Coding/Data Compression -- theory and algorithms
  3. Channel Coding/Error-Correcting Codes/Coding theory
  4. Rate-distortion theory.
  5. Miscellaneous advanced topics depending on time and interest (Kolmogorov Complexity, Universal Portfolio Theory, Network Coding, ...)

 

 

Content, highlighting fundamental concepts (not necessarily in the chronological order we will use in classroom discussions)

 

 

Topic

Contents/fundamental concepts

  • Information theoretic quantities

 

 

 

 

 

 

  • Lossless source coding

 

 

 

 

  • Channel coding

 

 

 

 

 

  • Rate-distortion theory

 

  • Entropy, conditional entropy, mutual information, divergence, differential entropy, Markov/ergodic sources, properties (chain rules, positivity, convexity, Jensen's inequality, Fano's inequality, conditioning, data processing inequality, Law of large numbers, Sanov's theorem, AEP, entropy rates) 

 

  • Achievability and converse proofs, Kraft inequality, codes -- Shannon-Fano-Elias, Huffman, Arithmetic, Lempel-Ziv (universal codes)

 

  • Hamming codes, channel capacity (achievability and converse proofs), zero-error capacity, joint source-channel coding, feedback capacity, Gaussian channels (parallel channels, coloured noise)

 

  • Scalar/vector quantization, rate-distortion theorem (achievability and converse)

 

Learning outcomes:

 

  1. Demonstrate ability to manipulate basic information-theoretic quantities to prove relevant theorems.
  2. Demonstrate understanding of foundational topics in information theory, and an ability to use the theoretic tools required to prove corresponding theorems.
  3. Use the above to characterize and design information storage, manipulation and transmission systems.

Feedback for evaluation:

Class evaluations

 

Students are welcome to express their comments and suggestions via the following formal and informal feedback channels:

 

 

  • Two course evaluations. First one to be conducted in the middle of the term and the second one at the end of the term. Students are encouraged to provide specific comments and/or suggestions in addition to the numeric ratings.
  • At the end of each lecture there will be a single question feedback slip given to each student.
  • Students are also encouraged to provide feedbacks using informal channels, such as email/discussion to instructor/tutor, and via the talk pages on the class wiki.
