Paper in AISTATS 2013 on “Beyond Sentiment: The Manifold of Human Emotions”

Sentiment analysis predicts the presence of positive or negative emotions in a text document. In this paper we consider higher-dimensional extensions of the sentiment concept, which represent a richer set of human emotions. Our approach goes beyond previous work in that our model contains a continuous manifold rather than a finite set of human emotions.

Paper in ICCP 2013 “Post-processing approach for radiometric self-calibration of video”

We present a novel data-driven technique for radiometric self-calibration of video from an unknown camera. Our approach self-calibrates radiometric variations in video, and is applied as a post-process; there is no need to access the camera, and in particular, it is applicable to internet videos.
