The checkerboard copula and dependence concepts

no code implementations23 Apr 2024 Liyuan Lin, Ruodu Wang, Ruixun Zhang, Chaoyi Zhao

We study the problem of choosing the copula when the marginal distributions of a random vector are not all continuous.

Towards Efficient Diffusion-Based Image Editing with Instant Attention Masks

1 code implementation15 Jan 2024 Siyu Zou, Jiji Tang, Yiyi Zhou, Jing He, Chaoyi Zhao, Rongsheng Zhang, Zhipeng Hu, Xiaoshuai Sun

In particular, InstDiffEdit aims to employ the cross-modal attention ability of existing diffusion models to achieve instant mask guidance during the diffusion steps.
