Lecture 1: Introduction and Probability Review
Lecture 1: Introduction and Probability Review
Description: Probability, as it appears in the real world, is related to axiomatic mathematical models. Events, independence, and random variables are reviewed, stressing both the axioms and intuition. Instructor: Prof. Robert Gallager
Lecture 23: Martingales (Plain, Sub, and Super)
Lecture 23: Martingales (Plain, Sub, and Super)
Description: After reviewing Wald's identity, we introduce martingales and show they include many processes already studied. Next, submartingales, supermartingales, and stopped (simple, sub, super) martingales are introduced. Instructor: Prof. Robert Gallager
Lecture 5: Poisson Combining and Splitting
Lecture 5: Poisson Combining and Splitting
Description: In this lecture, many problem solving techniques are developed using, first, combining and splitting of various Poisson processes, and, second, conditioning on the number of arrivals in an interval. Instructor: Prof. Robert Gallager
