Diffusion Autoencoders: Toward a Meaningful and Decodable Representation

2 code implementations • CVPR 2022 • Konpat Preechakul, Nattanat Chatthee, Suttisak Wizadwongsa, Supasorn Suwajanakorn

Our key idea is to use a learnable encoder for discovering the high-level semantics, and a DPM as the decoder for modeling the remaining stochastic variations.

NeX: Real-time View Synthesis with Neural Basis Expansion

1 code implementation • CVPR 2021 • Suttisak Wizadwongsa, Pakkapon Phongthawee, Jiraphon Yenphraphai, Supasorn Suwajanakorn

We present NeX, a new approach to novel view synthesis based on enhancements of multiplane image (MPI) that can reproduce next-level view-dependent effects -- in real time.

Accelerating Guided Diffusion Sampling with Splitting Numerical Methods

1 code implementation • 27 Jan 2023 • Suttisak Wizadwongsa, Supasorn Suwajanakorn

Guided diffusion is a technique for conditioning the output of a diffusion model at sampling time without retraining the network for each specific task.

Diffusion Sampling with Momentum for Mitigating Divergence Artifacts

1 code implementation • 20 Jul 2023 • Suttisak Wizadwongsa, Worameth Chinchuthakun, Pramook Khungurn, Amit Raj, Supasorn Suwajanakorn

The first technique involves the incorporation of Heavy Ball (HB) momentum, a well-known technique for improving optimization, into existing diffusion numerical methods to expand their stability regions.
