RAVEN: Rethinking Adversarial Video Generation with Efficient Tri-plane Networks

no code implementations11 Jan 2024 Partha Ghosh, Soubhik Sanyal, Cordelia Schmid, Bernhard Schölkopf

To capture these dependencies, our approach incorporates a hybrid explicit-implicit tri-plane representation inspired by 3D-aware generative frameworks developed for three-dimensional object representation and employs a singular latent code to model an entire video sequence.

Adversarial Likelihood Estimation With One-Way Flows

no code implementations19 Jul 2023 Omri Ben-Dov, Pravir Singh Gupta, Victoria Abrevaya, Michael J. Black, Partha Ghosh

Generative Adversarial Networks (GANs) can produce high-quality samples, but do not provide an estimate of the probability density around the samples.

Investigating self-supervised, weakly supervised and fully supervised training approaches for multi-domain automatic speech recognition: a study on Bangladeshi Bangla

no code implementations24 Oct 2022 Ahnaf Mozib Samin, M. Humayon Kobir, Md. Mushtaq Shahriyar Rafee, M. Firoz Ahmed, Mehedi Hasan, Partha Ghosh, Shafkat Kibria, M. Shahidur Rahman

We also demonstrate the significance of domain selection while building a corpus by assessing these models on a novel multi-domain Bangladeshi Bangla ASR evaluation benchmark - BanSpeech, which contains approximately 6. 52 hours of human-annotated speech and 8085 utterances from 13 distinct domains.

LED: Latent Variable-based Estimation of Density

no code implementations23 Jun 2022 Omri Ben-Dov, Pravir Singh Gupta, Victoria Fernandez Abrevaya, Michael J. Black, Partha Ghosh

Modern generative models are roughly divided into two main categories: (1) models that can produce high-quality random samples, but cannot estimate the exact density of new data points and (2) those that provide exact density estimation, at the expense of sample quality and compactness of the latent space.

InvGAN: Invertible GANs

no code implementations8 Dec 2021 Partha Ghosh, Dominik Zietlow, Michael J. Black, Larry S. Davis, Xiaochen Hu

Our \textbf{InvGAN}, short for Invertible GAN, successfully embeds real images to the latent space of a high quality generative model.

Populating 3D Scenes by Learning Human-Scene Interaction

1 code implementation CVPR 2021 Mohamed Hassan, Partha Ghosh, Joachim Tesch, Dimitrios Tzionas, Michael J. Black

Second, we show that POSA's learned representation of body-scene interaction supports monocular human pose estimation that is consistent with a 3D scene, improving on the state of the art.

Resisting Adversarial Attacks using Gaussian Mixture Variational Autoencoders

no code implementations31 May 2018 Partha Ghosh, Arpan Losalka, Michael J. Black

Our model has the form of a variational autoencoder, with a Gaussian mixture prior on the latent vector.

Learning Human Motion Models for Long-term Predictions

no code implementations10 Apr 2017 Partha Ghosh, Jie Song, Emre Aksan, Otmar Hilliges

Furthermore, we propose new evaluation protocols to assess the quality of synthetic motion sequences even for which no ground truth data exists.
