Mon-Wed 2:30-4:00 pm

Data mining is the analysis of (often large) observational datasets to find unsuspected relationships and to summarize the data in novel ways that are both understandable and useful to the data analyst (Hand, Mannila and Smyth: Principles of Data Mining)

The goal of this course is to provide an introduction to the main topics in data mining including: frequent-itemset mining, clustering, classification, link-analysis ranking, dimensionality reduction etc. The focus of the course will be on the algorithmic issues as well as applications of data mining to real-world problems. Students will be required to solve small written and programming assignments that will help them better understand the covered material.

Three programming projects

Three problem sets

Two exams; one midterm and one final

Working knowledge of programming and data structures (CS 112, or
equivalent). Familiarity with basic algorithmic concepts, probability,
statistics and linear algebra. Programming projects will require knowledge
of C (or C`), java or python.`

Many of these slides have been borrowed by lectures, talks and tutorials prepared by: Aris Anagnostopoulos, Petros Drineas, Piotr Indyk, George Kollios, Heikki Mannila, Panayiotis Tsaparas, Jeffrey Ullman.

The lectures on classification are using the slides from the book ‘‘Introduction to Data Mining" by Tan, Steinbach, Kumar, available here.
