Vagelis Papalexakis, graduate student
Hello! My name is Vagelis Papalexakis. I recently received the ECE Diploma degree from the Technical University of Crete.
I am now a post-graduate student @ the ECE department of TUC, under the supervision of professor Nikos Sidiropoulos.
This fall, I will be joining the Computer Science Department of Carnegie Mellon University as a PhD student.

My research is focused on the application of Signal Processing algorithms, Multiway Analysis, and Optimization methods to Data Mining and Co-clustering.

I completed my diploma thesis under the supervision of professor Nikos Sidiropoulos, with title "Reviewer Profiling Using Factor Analysis".
You can download the full text and the presentation slides, both in .pdf format.
I provide here a cvx-based implementation of the algorithms
used as basis for my thesis. I
also provide a demo of GoogleScholarMiner as presented on my thesis.
You need to have Matlab (and cvx, in the case of NMF & PARAFAC) installed, in order to execute the above files.
In the case of GoogleScholarMiner, you also need to have Java installed in your computer.
