Algorithms for Big Data (COMPSCI 229r), Lecture 9

Algorithms for Big Data (COMPSCI 229r), Lecture 9 This lecture explores sophisticated techniques for establishing space lower bounds for streaming algorithms using communication complexity. The discussion covers foundational concepts like one-way protocols, the index problem, and information theory tools required to analyze the space complexity of algorithms for tasks such as calculating distinct elements and median estimation.
