Hi! I'm Vikas Kumar, a PhD Candidate at GroupLens Research,
University of Minnesota, Twin Cities.

Recommendation Systems (Multimedia: Music, Movies and Images); Social Computing; Human Computer Interaction; Machine Learning and Information Retrieval.

Research

User interactions with online multimedia provide multiple aspects of users' dynamic preferences and behavior. My interest lies in understanding and modeling such dynamic preferences to build more effective music, movie or photo recommendations. Apart from analyzing user interactions, I am also exploring the importance of location in user behavior and establishing meaningful context for more diverse and novel recommendations.

  • #JelloResearchStatement

    Jello can be found in different color and shape. Wise jello-ers believe that people like Jello often of only certain color and shape. However, based on my jello experience, I find that my friends do not always like the same color and shape. And that, though they prefer the green Jello shots in round cups, they do sometime prefer the Jello of different shape and color. As I believed, I saw similar dilemma among various other jello lovers. Thus, I build a Jello maker that can make the right color and shape that my friends are likely to try.
