Learning What Not to Model: Gaussian Process Regression with Negative Constraints

no code implementations1 Jan 2021 Gaurav Shrivastava, Harsh Shrivastava, Abhinav Shrivastava

But, what if for an input point '$\bar{\mathbf{x}}$', we want to constrain the GP to avoid a target regression value '$\bar{y}(\bar{\mathbf{x}})$' (a negative datapair)?

Hierarchical Video Prediction Using Relational Layouts for Human-Object Interactions

no code implementations CVPR 2021 Navaneeth Bodla, Gaurav Shrivastava, Rama Chellappa, Abhinav Shrivastava

Our work builds on hierarchical video prediction models, which disentangle the video generation process into two stages: predicting a high-level representation, such as pose sequence, and then learning a pose-to-pixels translation model for pixel generation.

Diverse Video Generation using a Gaussian Process Trigger

1 code implementation ICLR 2021 Gaurav Shrivastava, Abhinav Shrivastava

Our approach, Diverse Video Generator, uses a Gaussian Process (GP) to learn priors on future states given the past and maintains a probability distribution over possible futures given a particular sample.

Video Dynamics Prior: An Internal Learning Approach for Robust Video Enhancements

no code implementations NeurIPS 2023 Gaurav Shrivastava, Ser-Nam Lim, Abhinav Shrivastava

In this paper, we present a novel robust framework for low-level vision tasks, including denoising, object removal, frame interpolation, and super-resolution, that does not require any external training data corpus.
