Research Works

BayesBeat: Reliable Atrial Fibrillation Detection from Noisy Photoplethysmography Data

Collaborators: Sarkar Snigdha Sarathi Das, Masum Rahman, Md. Saiful Islam, Dr. Atif Hasan Rahman, Mohammad Mehedy Masud, Dr. Mohammed Eunus Ali
This work focuses on reliable prediction on Photoplethysmography (PPG) signals that noisy due to motion artifacts. We have used Bayesian Deep Learning Model implemented in Python using PyTorch framework to provide an uncertainty estimate along with the prediction. We have also implemented a Tizen Native and Background Service App in C for continuous and timed raw signal data collection from Smartwatch. Our Model beats the state of the art work both on the largest publicly available dataset and on the MIMIC-III dataset. It was the first application of Bayesian Deep Learning in this domain.
Current state: Accepted in UbiComp 2022, Published in IMWUT

Privacy risk of Machine Learning Models

Supervisor: Dr. Shagufta Mehnaz
In this work we are experimenting on vulnerabilities and privacy risks of Trained Classification Models introduced particularly from Model Explainability. We explore potential application of various model explanation techniques like LIME, SHAP, Counterfactual Explanation etc. for implementing model inversion attacks. We are currently working on how we can generate a more robust attack dataset capable of leaking more information about the black box model using minimal knowledge about the training dataset. We are also exploring the direction in which LIME explanations can be exploited for property inference attacks.
Current state: Ongoing

Contrastive Learning Based Approach for Patient Similarity

Supervisor: Dr. Mohammed Eunus Ali, Dr. Atif Hasan Rahman
In this work we are experimenting on contrastive learning to learn patient similarity from physiological signals, particularly Photoplethysmography (PPG) signals. Due to limited availability of dataset, we are currently conducting a case study on Atrial Fibrillation Detection from PPG signals. It is the first application of Contrastive Similarity Learning in this domain.
Current state: Ongoing
