Data Compression and Entropy 2: Entropy as 'Question Game'

This lecture introduces the concept of entropy as a 'question game' where one must guess a randomly chosen letter by asking yes or no questions. Through examples and algorithms like Shannon-Fano, the instructor explains how entropy measures the minimum number of questions needed for guessing. The lecture also covers the relationship between entropy and data compression, illustrating how the frequency of letters in a sequence impacts the entropy value.
