Probabilistic models and tools are universally employed for design and understanding of both manmade and natural systems. Graduate research in many fields of electrical and computer engineering therefore requires a solid grounding in the mathematical basis for these tools. The goal of this course is to provide a concrete feel for the modeling and computations involved, as well as the kind of theoretical guarantees and approximations we can provide (e.g., convergence, limit theorems, optimal estimation), for stochastic systems.

(The course is mainly based on Chapters 1-4, 7, 8 of the text, but they are not necessarily covered in order, and we may sample some of the other chapters, time permitting.)

Homework: 20%
Probability Quiz: 5%
Midterm Exam: 30%
Final Exam: 45%
Collaboration on homeworks is allowed, but each student must turn in independently written solutions. Copying carries severe penalties. Homework will typically be assigned weekly, on or before Monday, and will be due in the course homework box the following Monday by noon. Late submissions will not be accepted.
Probability quiz: Tuesday, October 13 (the last half hour of class)
Midterm exam: Tuesday, November 3, 4-5:50 pm, in class
Final exam: Friday, December 11, 4-7 pm
(3 lectures)
