Active Research Projects

Research Themes: Develop artificial intelligence systems by advancing research in sensing, algorithms, scalable learning, and lightweight computation for edge devices. My focus is to enable critical real-world applications in the areas of water monitoring, semiconductor designing, precision agriculture, and ocean monitoring.

Multimodal Sensing and Machine Learning for Complex Data Analytics
In order to advance critical applications in water quality monitoring and human activity prediction, we are working on conducting fundamental research in real-time sensing, data analytics, and knowledge extraction. For water quality monitoring in collaboration with IBM Research and other research groups (https://researcher.watson.ibm.com/researcher/view_group.php?id=6924), we are developing a groundbreaking multi-sensor process for in-situ data collection without the need for laboratory analysis. We are also working on researching novel machine learning for human activity monitoring that can enable a new era in healthcare, fitness, and customized AI.
Developing Scalable Machine Learning Techniques
In this project, we are focussing on developing scalable machine learning to address critical applications like designing semiconductor chips and handling distributed databases. The complexity of modern semiconductor chips, with billions of transistors, has made manual verification of new chip designs nearly impossible. To automate the chip verification, we are developing new machine-learning research which is officially adopted by Arm (https://github.com/ARM-software/mango). Another direction that we are exploring in collaboration with Teradata is to allow machine learning models to be trained directly within the distributed database itself.
Enabling Lightweight Artificial Intelligence for Edge Devices
We are surrounded by edge devices including small robots, smartphones, smartwatches, airpods, cameras, speakers and wristbands, etc. Despite the potential of these edge devices to revolutionize various applications such as agriculture, ocean monitoring, and rescue operations, the limited memory and computation power of these devices has hindered the deployment of complex machine-learning algorithms. To address this, in this project, we are working on developing tiny machine-learning models. Our vision is to enable mobile robots equipped with various sensors (e.g., vision, audio, soil moisture, inertial measurement unit), and actuators (camera control, fertilizer dispenser, vehicle controls) to aid agricultural practices, ocean monitoring, and rescue operations in real-time.

We introduce Mango, a novel state-of-the-art ML Library for parallel hyperparameter tuning.

Mango handles categorical/discrete/continuous variables, enables CASH and alternative parallel searches.
Mango detects failures at the application layer for scalability on commodity hardware.

Mango is used in production to design ARM CPUs for IoT sensors to supercomputers, and from smartphones and laptops to autonomous vehicles.
