ECE 901 – Spring 2014

Statistical Learning Theory

Prerequisite: Background in applied mathematics, probability, and statistics

Office Hours: T-R 12:15-1pm

Meeting times:
Tuesday and Thursday 11am-12:15pm, room 2305 Engineering Hall

Course Format:
This course will serve as a primer for statistical learning theory as well as a platform
for exploring emerging theory and methods in large-scale data analytics. The course is
intended for PhD students in ECE, CS, Statistics and Mathematics who already have a strong
background in signal processing, machine learning, or mathematical statistics. The first
few weeks of the course will give an introduction to statistical learning theory (somewhat
following the lecture notes below). The rest of the course will involve reading and
discussion of a selection of papers. Each student will be responsible for reading all
papers and presenting a paper in the class.

Grading: Grades will be based on class participation, quizzes, homework assignments,
presentations and/or reports. Each student will be responsible for presenting one of the papers
that the class will study. Every student is required to carefully read the lecture notes and/or
papers prior to class lectures.
