On Inference Stability for Diffusion Models

2 code implementations19 Dec 2023 Viet Nguyen, Giang Vu, Tung Nguyen Thanh, Khoat Than, Toan Tran

To minimize that gap, we propose a novel \textit{sequence-aware} loss that aims to reduce the estimation gap to enhance the sampling quality.

Randomized Exploration for Reinforcement Learning with General Value Function Approximation

1 code implementation15 Jun 2021 Haque Ishfaq, Qiwen Cui, Viet Nguyen, Alex Ayoub, Zhuoran Yang, Zhaoran Wang, Doina Precup, Lin F. Yang

We propose a model-free reinforcement learning algorithm inspired by the popular randomized least squares value iteration (RLSVI) algorithm as well as the optimism principle.
