Data Scientist

• Apr 2018 - Sep 2018

• Analysing large amount of spatial, time and frequency domaindata and modelling physiological events faced by fighter jets pilots. • Implemented several python scripts to clean, pre-process and transform data collected during the fight jet missions for storage and data analysis. • Developed a data base to store non-uniform and unstructured data from multiple sources associated with various flight missions. • Used exploratory, cross-correlation and advanced clustering techniques to identify patterns in the data to predict harmful physiological events. • Developed various time -synchronization and resampling schemes to align data for analysis and modelling. • Setting up dash board for visualizing and presentations and writing high quality reports for middle and high level management presentations. • Working on various modern methodologies in dimension reduction to handle large feature space and to build a parsimonious s model for root-cause analysis and prediction of rare physiological events.

Senior Algorithmic Engineer

• Jun 2017 - Mar 2018

• Analysed large set of image data to extract various patterns and empirical relationships in wavelet transform domains and developed context-based predictor models to improve the coding efficiency of the entropy coders (M-Coders, binary arithmetic coders). • Applied modern machine learning schemes such as Convolutional neural networks (CNN), logistic regression, SVM etc. to build various predictor models in wavelet transform domain. • Worked on various Embedded Video Coding Algorithms(Matlab/C++): EZW, SPIHT, EBCOT, SPECK • Designed a new architecture to improve the compression Rate of SPIHT algorithms used in the current Video Codec standards. • Researched into various quantization and rate-distortion based optimization schemes to improve the compression rates in the current video codec standards: MPEG, H.264, HEVC etc.
