Hi! I am Abhijit Suprem. I am a PhD student at Georgia Tech in the School of Computer Science. My advisor is Professor Calton Pu. I work on Systems for Machine Learning, which lies at intersection of databases, machine learning, and adaptive systems. I am currently working on EDNA, a toolkit for adaptive streaming workflows for machine learning. We use EDNA for several of our projects, including LITMUS disaster detection, Covid-19 analysis, and SAFR vehicle tracking.

Currently, I am working on two projects: (i) EDNA-Covid and (ii) EDNA-SAFR. EDNA-Covid is our real-time Covid-19 data collection and analysis application, running on the EDNA streaming toolkit. We started collecting data on January 25, 2020 and till date, we have collected over 600M tweets plus articles and reports from myriad sources. EDNA-SAFR is a traffic monitoring framework for heterogenous camera networks that performs its live video analytics on EDNA. EDNA-SAFR is designed for multi-camera vehicle tracking and event detection.

I have been fortunate enough to advise several brilliant students on their projects or research.

Student(s): Eric Gastineau
Project: Fixing GAN-based Data Augmentation
Context: MS Project, Georgia Tech, 2019-2020
Summary: GANs are useful in creating synthetic data, but there remains performance discrepancy between using real images versus using synthetic images for training object detectors/classifiers. This project is investigating dynamic compression methods to reduce the performance discrepancy.

Student(s): Shreeshaa Kulkarni, Elsa Smaci, Kanksha Zaveri, Jayanta Bhowmick, Mitesh Kothari
Project: Automatic Model Generation for Vehicle Re-ID
Context: Course Project, Georgia Tech, Fall 2019
Summary: Build a system for automated, end-to-end pipeline generation for vehicle re-id. For each camera in a heterogeneous camera network, a detection model is generated using camera profile. Simialrity, vehicles are tracked using compressed re-id models for real-time performance.

Student(s): Ka-Ho Chow, Anjian Peng, Xiao Feng
Project: LITMUS Wildfire
Context: Course Project, Georgia Tech, Fall 2019
