I am Alceu Costa, a PhD student in Computer Science at the University of São Paulo (USP) in Brazil. Part of my ongoing PhD project included a visiting period of one year at Carnegie Mellon University. Currently, I am researching data mining techniques to detect bots and fraudsters on social media based on temporal data. I am also working on modeling information cascades and user communication behavior.
My research interests include:
- Data mining (KDD);
- Modeling user behavior in social media;
- Image processing and computer vision;
I also like to take photos on my free time.
