Looking Similar, Sounding Different: Leveraging Counterfactual Cross-Modal Pairs for Audiovisual Representation Learning

no code implementations12 Apr 2023 Nikhil Singh, Chih-Wei Wu, Iroro Orife, Mahdi Kalayeh

We additionally compare this approach to a strong baseline where we remove speech before pretraining, and find that dub-augmented training is more effective, including for paralinguistic and audiovisual tasks where speech removal leads to worse performance.

Human Detection of Political Speech Deepfakes across Transcripts, Audio, and Video

no code implementations25 Feb 2022 Matthew Groh, Aruna Sankaranarayanan, Nikhil Singh, Dong Young Kim, Andrew Lippman, Rosalind Picard

Recent advances in technology for hyper-realistic visual and audio effects provoke the concern that deepfake videos of political speeches will soon be indistinguishable from authentic video recordings.

Image2Lego: Customized LEGO Set Generation from Images

no code implementations19 Aug 2021 Kyle Lennon, Katharina Fransen, Alexander O'Brien, Yumeng Cao, Matthew Beveridge, Yamin Arefeen, Nikhil Singh, Iddo Drori

In order to demonstrate the broad applicability of our system, we generate step-by-step building instructions and animations for LEGO models of objects and human faces.

Solving Machine Learning Problems

1 code implementation2 Jul 2021 Sunny Tran, Pranav Krishna, Ishan Pakuwal, Prabhakar Kafle, Nikhil Singh, Jayson Lynch, Iddo Drori

Our system demonstrates an overall accuracy of 96% for open-response questions and 97% for multiple-choice questions, compared with MIT students' average of 93%, achieving grade A performance in the course, all in real-time.

Image2Reverb: Cross-Modal Reverb Impulse Response Synthesis

1 code implementation ICCV 2021 Nikhil Singh, Jeff Mentch, Jerry Ng, Matthew Beveridge, Iddo Drori

Measuring the acoustic characteristics of a space is often done by capturing its impulse response (IR), a representation of how a full-range stimulus sound excites it.

Parametric Regression on the Grassmannian

no code implementations14 May 2015 Yi Hong, Nikhil Singh, Roland Kwitt, Nuno Vasconcelos, Marc Niethammer

We then specialize this idea to the Grassmann manifold and demonstrate that it yields a simple, extensible and easy-to-implement solution to the parametric regression problem.
