Mayank Mishra

I am an MS in Robotics student at the Robotics Institute, Carnegie Mellon University advised by Prof. Srinivasa Narasimhan.

Before coming to Pittsburgh, I worked as a research assistant at the Indian Institute of Science, Bangalore, under the guidance of Prof. Venkatesh Babu. My work focused on improving the learning algorithms for deep neural networks by making them more generalizable on real-world datasets with class-imbalance.

Previously, I finished my undergraduate in computer science at the University of Petroleum and Energy Studies, Dehradun. I have also had the privilege to work under the direction of Dr. Tanupriya Choudhury and Dr. Tanmay Sarkar on various research projects focusing on the applications of computer vision.

Escaping Saddle Points for Effective Generalisation on Class-Imbalanced Data
Harsh Rangwani, Sumukh K Aithal, Mayank Mishra ,& R. Venkatesh Babu

Neural Information Processing Systems (NeurIPS'2022)

Examined the spectral density of Hessian of class wise loss to show network weights converges to a saddle point in the loss landscape of minority classes. Furthermore, showed that methods that encourage convergence to flatter minima can be used to escape saddle points for minority classes.

Allergen30: Detecting food items with possible allergens using deep learning based computer vision
Mayank Mishra, Tanmay Sarkar, Tanupriya Choudhury, Nikunj Bansal, Slim Smaoui, Maksim Rebezov, Mohammad Ali Shariati&, Jose Manuel Lorenzo

Journal: Food Analytical Methods (SCI, IF 3.5, Springer)

Introducing Allergen30, a custom-made dataset with 6,000+ images of 30 commonly used food items that can trigger an allergic reaction within the human body. This work is one of the first research attempts to train a deep learning based object detection model to detect the presence of such food items from images.

Articles
Computer Vision: Image formation and representation
Article chosen for further distribution by Medium

This article discusses the introductory topics of Computer Vision, namely image formation and representation. The image formation section briefly covers how an image is formed and the factors on which it depends. It also covers the pipeline of image sensing in a digital camera. The second half of the article discusses various ways of image representation and focuses on certain operations that can be performed on images.
