CSE 255: Dahta Mining and Predictive Analytics

Winter 2015, Mondays 18:30-21:20, CENTR 222

For the current version of this class, see here

CSE 255 is a graduate-level course devoted to current methods for data mining and predictive analytics. No previous background in machine learning is required, but all participants should be comfortable with programming (all example code will be in Python), and with basic optimization and linear algebra.

The course meets once a week on Monday evening, starting January 5. There will be no classes on January 19 (MLK day) or on February 16 (President's day). Meetings are in CENTR 222.

There is no textbook for the course, though chapter references will be provided from Pattern Recognition and Machine Learning (Bishop), and from Charles Elkan's 2013 course notes.

Office hours: I'll hold office hours on Friday 9-11am in CSE 4102. Additional office hours will be held by Dongcai Shen on Mondays 10-12 in CSE 4127. For other discussions see the course's Piazza page.
