Information Theory
About The Course Information theory is the science of operations on data such as compression, storage, and communication. It is among the few disciplines fortunate to have a precise date of birth: 1948, with the publication of Claude E. Shannon's paper entitled "A Mathematical Theory of Communication". Our course will explore the basic concepts of Information theory. It is a prerequisite for resea
