Optimal Transport-Guided Conditional Score-Based Diffusion Models

1 code implementation2 Nov 2023 Xiang Gu, Liwei Yang, Jian Sun, Zongben Xu

Conditional score-based diffusion model (SBDM) is for conditional generation of target data with paired data as condition, and has achieved great success in image translation.

DeepFire2: A Convolutional Spiking Neural Network Accelerator on FPGAs

no code implementations9 May 2023 Myat Thu Linn Aung, Daniel Gerlinghoff, Chuping Qu, Liwei Yang, Tian Huang, Rick Siow Mong Goh, Tao Luo, Weng-Fai Wong

Brain-inspired spiking neural networks (SNNs) replace the multiply-accumulate operations of traditional neural networks by integrate-and-fire neurons, with the goal of achieving greater energy efficiency.

Generalized Semantic Segmentation by Self-Supervised Source Domain Projection and Multi-Level Contrastive Learning

1 code implementation3 Mar 2023 Liwei Yang, Xiang Gu, Jian Sun

SSDP aims to reduce domain gap by projecting data to the source domain, while MLCL is a learning scheme to learn discriminative and generalizable features on the projected data.

A Unified Hyper-GAN Model for Unpaired Multi-contrast MR Image Translation

1 code implementation26 Jul 2021 Heran Yang, Jian Sun, Liwei Yang, Zongben Xu

Hyper-GAN consists of a pair of hyper-encoder and hyper-decoder to first map from the source contrast to a common feature space, and then further map to the target contrast image.
