Hi, This is ImtiazI'm a machine learning enthusiast/advocate in my first year of PhD with Dr. Richard Baraniuk at Rice University. Previously, I worked as a Research Assistant at the mHealth Research Group, Department of Biomedical Engineering, Bangladesh University of Engineering and Technology (BUET). I have completed my Bachelor's in Electrical and Electronic Engineering from BUET in September 2017. My research interests include Computer Vision, Biomedical Signal Processing, Domain Adaptation, Low Resource Speech Recognition and Music Information Retrieval.
Rashed, Samiul and I started working on Bengali.AI from December 2017 and have been leading this platform ever since. In my free time I love playing Sitar, and quite recently I have started self learning (read failing at) piano.
My research mainly involves injecting signal processing intuition into Convolutional Neural Networks to adapt them for low resource tasks. A key problem for biomedical engineering tasks is the scarcity and domain dependency of data. Removal of domain dependency is key to widespread deployment of AI algorithms, namely, in mobile healthcare applications. My research is currently focused on conditioning CNNs so that the features learned by them lie between handcrafted features and generic CNN features, to ensure better generalization and less dependency on the domains/sensors.
Biomedical data is at the mercy of the acquisition device. A model trained on data from one device tends to perform below par on data from a different one. This is a common problem when the volume of data is low and data from different devices are not available. I’m experimenting an adversarial domain adaptation method where a conditional adversarial discriminator forces the model to derive domain agnostic features.
Interpretable Machine Learning
Interpretability of machine learning algorithms, especially, neural networks, has been of utmost interest to researchers in recent years. My research explores the interpretability of 1DCNNs from a Finite Impulse Response/Signal Processing perspective.
mHealth and Pervasive Application
Mobile Healthcare (mHealth for short) deals with the application of healthcare systems in setups where the availability of physicians is scarce. Cardiovascular diseases are one of the major causes of death in Bangladesh, mostly due to the scarcity of trained cardiologists who can diagnose a cardiac anomaly at an early stage. My work incorporates deploying deep learning models for pre-screening of patients for cardiac abnormality.
Computer Vision for Assistive Technologies
Embedded Application of Computer Vision Algorithms have wide potential in assistive technologies. Two key challenges remain vital for the success and outreach of such technologies: real-time algorithms and the price tag. My research incorporated the use of cheap webcams with a real-time embedded application. It also utilized Head Related Transfer Functions to modulate stereo sounds for blind assistance.
Music Information Retrieval
Music Information Retrieval is the field of research that enables your Shazam, that powers your Spotify recommendations. I was introduced to it through the IEEE Signal Processing Cup 2017, and have fallen in love with it ever since. My interests lie in cover song identification and music beat tracking.
