Welcome to all of the new ECE graduate students at NYU Poly! I am very excited to be teaching EL 6303, "Probability and Stochastic Processes", the most important core course in ECE, and I look forward to having you in class!
This course is the fundamental core course for all degrees in ECE, and you must master this material to succeed in graduate school, in research, and in life. I encourage students to buy the book early, and begin reading the book (4th edition US edition) *before* our first day of class. I will hold weekly help sessions on Monday and Friday afternoons, and we will work lots of problems, I will hold extra office hours, and we will have TAs to help everyone master the material, but you will have to work hard. This is a challenging and rigorous class; it is also required class for your program. Come prepared to work and to learn this wonderful field!
To ensure knowledge and learning, will be held on Friday’s and Monday’s every week. Be sure to attend these help sessions to be sure you are learning the material. You want to come to these help sessions as many problems will be worked for practice and understanding!
Help Sessions : 2 Metrotech Center Classroom 9.009, Mondays 122PM and Fridays 12 – 2 PM. (There will be no help session on Friday October 4th, 2013.)
In addition to this website please see blackboard for additional resources.
