Intern, Machine Learning: Upstream Tech Aug 2018 –Present

Technologies: Keras, Tensor board, CNN, Rasters, Git version control

Worked on removing speckle noise in image tiles from obtained Synthetic Aperture Radars using Convolutional Neural Networks (CNN)

Conducted proof of concept to identify an appropriate network architecture to train a deep learning model without having to use clean targets. Obtained a fairly clear version of the noisy tiles with PSNR value nearly 32dB.

A short write-up on my work:

Currently working on sentinel-1 and sentinel-2 data fusion to obtain better Landcover mappings. Using Convolutional Neural Networks to perform mapping between Sentinel-1 and Normalized Vegetation Index data.

Intern, Machine Learning: Verint Systems, WA Jun 2018 - Aug 2018

Technologies: Python, Keras, scikit-learn, NLTK, GloVe, Linux, Pool, Flask Rest-API, Docker

Trained a multi-class, multi-label, powerful LSTM classifier to perform Sentiment classification and POS tagging based off a virtual agent’s chat corpus data. Also trained phrasal Glove embeddings to be used as input features to the model

Improved the model’s performance using Active Learning. Delivered the functionality as a REST API service.

Developed a scalable, distributed query strategy technique to sample from nearly 20M unlabelled chat data records and improved run time by 45% using parallel processing

Research Intern: Centre for Development of Advanced Computing (C-DAC), India Dec 2016 - Apr 2017

Technologies: R, e1071, JSP, Java Servlets, PostgreSQL, Android Studio

Designed and implemented Risk Based Authentication system (Anomaly Detection) which improves online security using One-class Support Vector Machine, Naïve-Bayes model.

The authentication token was implemented as an android application

The project was presented in the 14th IEEE International Conference on Advanced Trusted Computing, San Francisco, USA. Had rave positive reviews at the conference
