I am a first year Ph.D. student in the Robotics Institute (RI) at Carnegie Mellon University (CMU), working with Prof. Shubham Tulsiani. I graduated with a Master of Science in Robotics (MSR) from the Robotics Institute (RI) at Carnegie Mellon University (CMU) where I worked with Prof. Abhinav Gupta and collaborated with Prof. Pedro Morgado at UW-Madison. Previously, I worked as a Research Assistant at CMU with Prof. David Held at the R-Pad Lab, in collaboration with Pittsburgh-based autonomous driving company, Argo AI. During my Masters at CMU, I am working on self-supervised representation learning methods for multimodal audio-visual videos. Previously, as a RA at CMU, I worked on self-supervised algorithms for 3D LiDAR point clouds. I did my bachelors from Jaypee Institute of Information Technology, Noida, India where I worked with Dr. Anuja Arora. |

I am interested in self-supervised learning, multi-modal machine learning, video representation learning, generative models, point clouds and autonomous driving. |

Himangi Mittal, Pedro Morgado, Unnat Jain, Abhinav Gupta [NeurIPS 2022] ECCV 2022 Workshop on Visual Object-oriented Learning meets Interaction (VOLI): Discovery, Representations, and Applications Sight and Sound Workshop (CVPR 2023) Arxiv / Code / Video We propose a self-supervised algorithm to learn representations from untrimmed, egocentric videos containing audible interactions. Our method uses the audio signals in two unique ways: (1) to identify moments in time that are conducive to better self-supervised learning and (2) to learn representations that focus on the visual state changes caused by audible interactions. |

Himangi Mittal, Brian Okorn, Arpit Jangid, David Held [BMVC 2021 - Oral (Selection rate 3.3%)] Paper / Arxiv / Code / Conference Presentation / Webpage A self-supervised method to complete the incomplete, partial point clouds for real-world settings like LiDAR where ground truth complete point cloud annotations are unavailable. We achieve this via inpainting where a region of the point cloud is removed and the network is trained to complete this removed region. |
