Radhika Dua

Hi, I am a Master's student in Graduate School of AI at Korea Advanced Institute of Science and Technology (KAIST). I am fortunate to have Prof. Edward Choi as my advisor. I am interested in Artificial Intelligence at the intersection of Computer Vision, Machine Learning & Healthcare. I am currently working on out-of-distribution detection in deep learning.

Before joining KAIST, I was a Summer Intern at Brown University, where I was fortunate to be advised by Prof. Srinath Sridhar. Prior to my time at Brown University, I was a Visiting Researcher at IIT Hyderabad, where I was blessed to be supervised by Prof. Vineeth N Balasubramanian.

Natural Attribute-based Shift Detection.
Jeonghoon Park*, Jimin Hong*, Radhika Dua*, Daehoon Gwak, Yixuan Li, Jaegul Cho, Edward Choi
Under Review 2021

We define a new task, natural attributebased shift (NAS) detection, to detect the samples shifted from the training distribution by some natural attribute such as age of subjects or brightness of images. We also introduce benchmark datasets in vision, language, and medical for NAS detection.

Beyond VQA: Generating Multi-word Answer and Rationale to Visual Questions.
Radhika Dua*, Sai Srinivas Kancheti*, Prof. Vineeth N Balasubramanian
MULA Workshop, CVPR 2021
Paper / Slides / Video / Poster

We introduce a new task: ViQAR (Visual Question Answering and Reasoning), wherein a model must generate the complete answer and a rationale that seeks to justify the generated answer.

VayuAnukulani: Adaptive Memory Networks for Air Pollution Forecasting
Radhika Dua*, Divyam Madaan*, Dr. Prerana Mukherjee
GlobalSIP, 2019
Paper / Code / slides

We present VayuAnukulani system, a novel end-to-end solution to forecast fine-grained ambient air quality information based on the historical and realtime ambient air quality and meteorological data.

Summer Intern, Brown University
Supervisor: Prof. Srinath Sridhar

Conducting research in 3D computer vision and machine learning.

Research Intern, Indian Institute of Technology, Hyderabad
Supervisor: Prof. Vineeth N Balasubramanian

Conducting research in Vision and Language applications and introduced a new task, ViQAR: Visual on Answering and Reasoning, which focuses on automatic generation of the answer, and of a rationale, given a visual query.

Research Intern, Celestini Project India
Mentor: Dr. Aakanksha Chowdhery (Google Brain and Tensorflow) and Prof. Brejesh Lall (IIT Delhi).
Sponsors:Marconi Society and Google

Developed a temporal forecasting solution based on the historical data reported by Central Pollution Control board to predict the real-time and fine-grained air quality information in five locations of Delhi.

CS6360: Advanced Topics in Machine Learning - Spring 2020
Instructor: Prof. Vineeth N Balasubramanian

CS5370: Deep Learning for Computer Vision - Fall 2019
Instructor: Prof. Vineeth N Balasubramanian
ViQAR: Visual Question Answering and Reasoning
Radhika Dua, Sai Srinivas Kancheti, Prof. Vineeth N Balasubramanian

We introduced a new task, ViQAR, in which the model generates the complete answer and rationale. We also proposed an end-to-end, attention-based encoder-decoder architecture to solve this task, and showed that our model generates strong answers and rationales through qualitative and quantitative evaluation, as well as human Turing Test.

Clair: Air Pollution Prediction
Radhika Dua, Divyam Madaan, Dr. Aakanksha Chowdhery

As a part of the Celestini Project, sponsored by Google and Marconi Society and mentored by Dr. Aakanksha Chowdhery, we developed Clair: Air pollution forecasting in Delhi, a temporal forecasting solution based on the historical data reported by Central Pollution Control board to predict the real-time and fine-grained air quality information in five locations of Delhi. We were awarded Second Prize for our novel solution and also had the opportunity of presenting our work at GlobalSIP 2019.
