Research Work

Canary - Software Suite for Data Mining Education The Canary Software Suite helps data mining students experiment with data mining algorithms. Canary is written in standard C++ and uses a graphical user interface developed with Qt. Each algorithm is packaged separately and can be used as a stand-alone application.

R Learning Infrastructure This project will develop an infrastructure that can help individuals easily learn and use R and RStudio. This infrastructure will include elements like: concept descriptions [modules], tutorials, exercises, resources, and references.
