Ankit Goyal

I am a Ph.D. student in Computer Science at Princeton University. I am a member of Princeton Vision and Learning Lab, advised by Prof. Jia Deng. I completed my Masters in CSE from University of Michigan and Bachelors in EE from IIT Kanpur. Previously, I have interned at Microsoft Research India with Prateek Jain in Summer 2016 and with Shrikanth Narayanan and Tanaya Guha at USC in Summer 2015.

Research

I am interested in understanding various aspects of intelligence, especially reasoning and common sense. In particular, I want to develop computation models for various reasoning skills that humans possess.

	Rel3D: A Minimally Contrastive Benchmark for Grounding Spatial Relations in 3D Ankit Goyal, Kaiyu Yang, Dawei Yang, Jia Deng NeuRIPS 2020, Spotlight (Top 4% of submitted papers) [code] [slides] [poster] Understanding spatial relations is important for both humans and robots. We create Rel3D, the first large-scale, human-annotated dataset for grounding spatial relations in 3D. The 3D scenes in Rel3D come in minimally contrastive pairs: two scenes in a pair are almost identical, but a spatial relation holds in one and fails in the other.
	PackIt: A Virtual Environment for Geometric Planning Ankit Goyal, Jia Deng ICML 2020 [code] [slides] [video] Simultaneously reasoning about geometry and planning action is crucial for intelligent agents. This ability of geometric planning comes in handy while grocery shopping, rearranging room, warehouse management etc. We create PackIt, a virtual environment that caters to geometric planning.
	Think Visually: Question Answering through Virtual Imagery Ankit Goyal, Jian Wang, Jia Deng ACL 2018 [code] [poster] We study geometric reasoning in the context of question-answering. We introduce Dynamic Spatial Memory Network (DSMN), a deep network architecture designed for answering questions that admit latent visual representations.
	ProtoNN: Compressed and Accurate kNN for Resource-scarce Devices C Gupta, AS Suggala, A Goyal, HV Simhadri, BP, AK, SG, RU, MV, P Jain ICML 2017 [code] Resource-Efficient Machine Learning Prateek Jain, Chirag Gupta, AS Suggala, Ankit Goyal, HV Simhadri US Patent Applicaiton We propose ProtoNN, a novel algorithm that addresses the problem of real-time and accurate prediction on resource-scarce devices.
	A Multimodal Mixture-Of-Experts Model for Dynamic Emotion Prediction in Movies Ankit Goyal, Naveen Kumar, Tanaya Guha, Shrikanth S. Narayanan ICASSP 2016 We address the problem of continuous emotion prediction in movies. We propose a Mixture of Experts (MoE)-based fusion model that dynamically combines information from the audio and video modalities for predicting the emotion evoked in movies.
	Object Matching Using Speeded Up Robust Features NK Verma, Ankit Goyal, A Harsha Vardhan, Rahul Kumar Sevakula, Al Salour IES 2016 We propose a robust algorithm which is capable of detecting all the instances of a particular object in a scene image using Speeded Up Robust Features.
	Template Matching for Inventory Management using Fuzzy Color Histogram and Spatial Filters NK Verma, Ankit Goyal, Anadi Chaman, Rahul K Sevakula, Al Salour ICIEA 2015 We propose a methodology for object counting using color histogram based segmentation and spatial filters.
