Learning from Massive, Incompletely Annotated, and Structured Data

Deals with image retrieval, deep learning, Twitter sentiment analysis, emotion identification on Twitter messages, and web genre predictions.

Twitter Sentiment Analysis Using Deep Convolutional Neural Network

With this, we can perform a Twitter sentiment analysis using a deep convolution neural network. The method is general and it can be applied on different short messages.

Content-based Image Retrieval for Large Medical Image Corpus

In this project, we address the scalability issue when it comes to content-based image retrieval in large image archives in the medical domain. Throughout the text, we focus on explaining how small changes in image representation, using existing technologies, leads to impressive improvements when it comes to image indexing, searches, and retrieval duration.

An Extensive Experimental Comparison of Methods for Multi-label Learning

This deals with a deep understanding of methods for multi-label learning. This evaluation is in the most cited papers in Pattern Recognition (one of the best artificial intelligence journals).

Evaluation of Different Feature Sets for Gait Recognition Using Skeletal Data from Kinect

In this project, we targeted the problem of gait recognition using skeletal data from Kinect.
