Instructor: Mary Wootters
TA: Reyna Hulett
When and where? T/Th 10:30-11:50am, Sapp Center for Science Teaching and Learning (STLC), Room 119.
Course Description: Introduction to the theory of error correcting codes, emphasizing algebraic constructions and diverse applications throughout computer science and engineering. Topics include basic bounds on error correcting codes; Reed-Solomon and Reed-Muller codes; list-decoding, list-recovery and locality. Applications may include communication, storage, complexity theory, pseudorandomness, cryptography, streaming algorithms, group testing, and compressed sensing.
Prerequisites: Linear algebra, basic probability (at the level of, say, CS109, CME106 or EE178) and "mathematical maturity" (students will be asked to write proofs). Familiarity with finite fields will be helpful but not required.
What do I need to do? Three homework assignments and a final project.
The following is a tentative schedule. It is subject to change, especially the lectures that have not happened yet.
