Currently, doing postdoc at University of Central Florida under Dr. Mubarak Shah . I completed my PhD at Visual Computing Lab, CDS, Indian Institute of Science, under the supervision of Prof. Anirban Chakraborty. Prior to that I completed my M.Tech from Jawarharlal Nehru University under the guidance of Prof. R. K. Agrawal, and B.Tech from VIT University in computer science. My area of research focuses on Artificial Intelligence at the intersection of Computer Vision, Machine Learning and Deep Learning.
Research
The performance of any deep learning model depends heavily on the data, using which it has been trained. The quality of the trained deep models improve with the availability of large number of uncorrelated datapoints. If the data available for training is not sufficiently large, the deep models overfit and do not generalize. Evidently, data plays a very crucial role in training any deep neural network model. However, data is ‘precious’, and may not be freely available all the time. Many companies have proprietary rights over their data. For example, models trained by Google and Facebook might utilize proprietary data such as JFT-300M, SFC. Also, the data may not be shared if it contains sensitive information, specially, when dealing with biometric data of large population, healthcare data of patients etc. In a nutshell, data is often more precious than anything else in the era of deep learning and hence efficient utilization of data is of utmost importance. My research work in my PhD, therefore, looked into developing data efficient deep learning algorithms for computer vision tasks and was supported by fellowship from UGC-NET (JRF).
