Case-study of Offensive Language Classification from Online Tweets

Here we try to analyze different approaches of online tweet classification into offensive and non-offensive categories in the presence of emoticons. We try to enhance the tokenization process to capture better sparsity in the presence of non-textual corpus.

Data Augmentation using Feature Generation for Volumetric Medical Images

In this work, we propose using U-net and ACGAN as a learning framework for feature generation of medical images followed by classification to validate the quality of generated features.

Enhancing clinical information retrieval on health forums using neural ranking models

Since health forums become a rich source of information to people with medical conditions discussing treatments, doctor's opinions, side-effects to complex-drugs, while also sharing personal background medical information in a community question-answering framework, we develop a neural search engine on top of such health forums by exploring the state-of-the-art neural ranking models. We first write a set of optimal heuristic functions that maximizes the relevancy scores for a labelled dataset by training a snorkel classifier that classifies a given query-document pair as relevant or irrelevant. Later, these functions are extended to classify the unlabelled set of query-document pairs, followed by re-ranking using neural re-rankers.

Music Information Retrieval For Genre Classification

We implement k-nearest neighbors, Gaussian Mixture Model, Multi-class SVM, Convolutional Neural Network, and Convolutional Recurrent Neural Network to classify the following four genres- Dark-Forest, Hi-Tech, Full-On, and Goa. We further extract 30 temporal features using a Long Short Term Memory based Auto encoder from individual frames, and augment them with the frame-level audio features, which is a novel contribution in this work.
