Accelerated Risk Management System for Audit Engagements

Jul 2015 - Jul 2016 (1 years 0 months)

Building a risk measurement system to assess engagements for professional services company Objective of the work is to develop a model to classify specific sentences in official engagements from over 40,000 documents into safe or risky. At an overall level, predict the anomaly index of the document and construct a feedback decision system for reviewing an engagement

Student Response Analysis using Textual Entailment

Sep 2013 - Nov 2013 (0 years 2 months)

To recognize the extent of correctness of a student answer given a question and a few reference
answers, used a combination of overlap measures and semantic similarity metrics utilising parse
trees, WordNet hierarchies and Explicit Semantic Analysis which represents text as a vector of
Semantic concepts learnt using LSA. The obtained accuracy was as good as the team positioned third in the Semeval 2013 task.

Recognizing Hand Written Characters and Numerals

Sep 2013 - Nov 2013 (0 years 2 months)

To classify handwritten digits using the famous MNIST data consisting of handwritten images of English alphabets and numerals. Deployed standard machine learning classifiers such as SVM, Neural Nets, k-NN and hybrid classifiers like Ada Boost on extracted dominant features to decrease error, given limitation on the run time of algorithm.

Voice Activity Detection using Deep Belief Networks by Source and System Level Information Fusion

Jul 2014 - Jun 2015 (0 years 11 months)

Built efficient Voice Activity Detection (VAD) models using Deep Belief Networks for classifying speech signal at very low SNR (<5dB) levels. Established the importance of fusing laryngeal originated source features with features from vocal tract in training a VAD model. Various experiments were performed with several feature sets. The results were evaluated in non-stationary noise conditions and compared with state-of-the-art VAD algorithms.
