OmniMotionGPT: Animal Motion Generation with Limited Data

CVPR 2024poster

Our paper aims to generate diverse and realistic animal motion sequences from textual descriptions without a large-scale animal text-motion dataset. While the task of text-driven human motion synthesis is already extensively studied and benchmarked it remains challenging to transfer this success to…

Learning Probabilistic Models from Generator Latent Spaces with Hat EBM

NeurIPS 2022accept

This work proposes a method for using any generator network as the foundation of an Energy-Based Model (EBM). Our formulation posits that observed images are the sum of unobserved latent variables passed through the generator network and a residual random variable that spans the gap between the gene…

Stochastic Security: Adversarial Defense Using Long-Run Dynamics of Energy-Based Models

ICLR 2021poster

The vulnerability of deep networks to adversarial attacks is a central problem for deep learning from the perspective of both cognition and security. The current most successful defense method is to train a classifier using adversarial images created during learning. Another defense approach involve…

Divergence Triangle for Joint Training of Generator Model, Energy-Based Model, and Inferential Model

CVPR 2019oral

This paper proposes the divergence triangle as a framework for joint training of a generator model, energy-based model and inference model. The divergence triangle is a compact and symmetric (anti-symmetric) objective function that seamlessly integrates variational learning, adversarial learning, wa…

Learning Non-Convergent Non-Persistent Short-Run MCMC Toward Energy-Based Model

NeurIPS 2019poster

This paper studies a curious phenomenon in learning energy-based model (EBM) using MCMC. In each learning iteration, we generate synthesized examples by running a non-convergent, non-mixing, and non-persistent short-run MCMC toward the current model, always starting from the same initial distributio…
