Carnegie Mellon University
15-826: Multimedia Databases and Data Mining
Fall 2012 - C. Faloutsos
The course covers advanced algorithms for learning, analysis, data
management and visualization of large datasets. Topics include
indexing for text and DNA databases, searching medical and
multimedia databases by content, fundamental signal processing
methods, compression, fractals in databases, data mining, privacy
and security issues, rule discovery, data visualization, graph
mining, stream mining.

METHOD OF EVALUATION
The course involves
- A midterm (20%)
- Homeworks (10%)
- A Project (40%)
- A Final exam (30%)
- Some homeworks will be indicated as mandatory, that is,
a passing grade is necessary.
- Projects will be carried out in teams of 3. A detailed
handout about the project will be distributed at the beginning of
the course, along with a list of suggested projects. The goal of
the project is to give the participants the opportunity to tackle a
large, interesting problem, which may lead to a publication.
