Disease Progression Modeling Using Attention-based Deep Learning Models

Developed a deep learning model for application to patients' medical record data, giving providers clinically interpretable and highly accurate disease predictions. The predictive modeling was trained on 90 million patient histories, and the models are in production for 15 chronic diseases.

Automatic Multilingual Query Answering System

Designed and implemented query resolution and response generation components that contribute to the intent classification and entity extraction components in a multilingual query answering system designed for a contact center.

Estimation of Airline Flight Delays Using Deep Learning Methods

Developed deep learning models, using TensorFlow for time-series predictions to estimate the cascade effect of flight delays in the airline business. Used transfer learning to generalize the model for multiple clients.

Fake News Detection System

Designed, implemented, and patented a fake news detection system that identifies fake news articles, using a set of Genomes Online Databases (GOLD). Used deep learning-based language models, such as BERT, to implement a stance detection model.

Custom Labeling of Images at Scale

Developed an automated workflow to pull product images from an AWS server; run them through an image recognition service (e.g., AWS Rekognition); validate those labels, at scale, using human moderated systems; and deliver corresponding labels for the product from an established list of acceptable labels, using AWS Lambda.

Object Detection and Segmentation for Retail Industry

A custom object detection and segmentation vision model deployed on AWS using SageMaker, Lambda functions, and custom automated labeling jobs to collect enough data to train the model. The deployment was done on Amazon accelerated compute engines, which lowered the cost dramatically.

Entity Extraction and Linking from Unstructured and Image Data

Led a team of data scientists to develop a document understanding, information and data extraction from PDF files (identifying the context), NLP, and Named-entity recognition (NER) solution at scale.

News Personalization Using Deep FM
