Understanding Entropy & Information: Oxford Lecture Series 📊

In this lecture from Sam Cohen’s 3rd year ‘Information Theory’ course, one of eight we are showing, Sam asks: how do we measure the amount of information we learn by seeing the outcome of a random variable? Answer: this can be measured by the variable’s entropy (and related quantities), which we introduce.
