Staff • Lecturer – Kenneth Shum – http: //home. ie. cuhk. edu. hk/~wkshum/ – Office: SHB 736 (inside Institute of Network Coding) – Office hour: Wednesday afternoon 3 pm~4 pm. • Teaching Assistant – Huang Huaiyi – Office: SHB 702 Sept 2018 kshum 2
A rigorous treatment of probability • Kolmogorov’s 1933 monograph on the foundation of probability theory – http: //www. mathematik. com/Kolmogorov/0000. html • This course covers the materials in a typical graduate math course on probability theory – Based on measure theory – This course significantly overlaps with MATH 5011 Real Analysis I • Roughly half of the course is about mathematical analysis. Sept 2018 kshum 3
What this course is NOT about • This is not a course on Bayesian reasoning or statistical learning, decision making, etc. – Please refer to IERG 5130 • We will not talk about statistical modeling – This requires estimation of system parameters, goodness-of-fit tests, etc. – IERG 3050 • In this course we seldom compute a probability value numerically. Sept 2018 kshum 4
Applications • Mathematical statistics – Large-sample theory • Random graphs and complex networks • Analysis of low-density parity-check codes – Martingale theory • Financial mathematics – Stochastic calculus, Ito integral, Brownian motion • Machine Learning Sept 2018 kshum 5
