Accelerating Diffusion Sampling via Exploiting Local Transition Coherence

no code implementations12 Mar 2025 Shangwen Zhu, Han Zhang, Zhantao Yang, Qianyu Peng, Zhao Pu, Huangji Wang, Fan Cheng

To address this issue, we discover a new statistical relationship in the transition operator between adjacent steps, focusing on the relationship of the outputs from the network.

Lipschitz Singularities in Diffusion Models

no code implementations20 Jun 2023 Zhantao Yang, Ruili Feng, Han Zhang, Yujun Shen, Kai Zhu, Lianghua Huang, Yifei Zhang, Yu Liu, Deli Zhao, Jingren Zhou, Fan Cheng

Diffusion models, which employ stochastic differential equations to sample images through integrals, have emerged as a dominant class of generative models.

Dimensionality-Varying Diffusion Process

no code implementations CVPR 2023 Han Zhang, Ruili Feng, Zhantao Yang, Lianghua Huang, Yu Liu, Yifei Zhang, Yujun Shen, Deli Zhao, Jingren Zhou, Fan Cheng

Diffusion models, which learn to reverse a signal destruction process to generate new data, typically require the signal at each step to have the same dimension.

FORTAP: Using Formulas for Numerical-Reasoning-Aware Table Pretraining

1 code implementation ACL 2022 Zhoujun Cheng, Haoyu Dong, Ran Jia, Pengfei Wu, Shi Han, Fan Cheng, Dongmei Zhang

In this paper, we find that the spreadsheet formula, which performs calculations on numerical values in tables, is naturally a strong supervision of numerical reasoning.

Computationally Efficient Learning of Statistical Manifolds

1 code implementation22 Feb 2021 Fan Cheng, Anastasios Panagiotelis, Rob J Hyndman

By exploiting the connection between Hellinger/total variation distance for discrete distributions and the L2/L1 norm, we demonstrate that the proposed distance estimators, combined with approximate nearest neighbor searching, could largely improve the computational efficiency with little to no loss in the accuracy of manifold embedding.

MOFSRank: A Multiobjective Evolutionary Algorithm for Feature Selection in Learning to Rank

no code implementations wiley online library 2018 Fan Cheng, Wei Guo, and Xingyi Zhang

Then on the selected instance subsets, a multiobjective feature selection algorithm with an adaptive mutation is developed, where good feature subsets are obtained by selecting the features with high ranking accuracy and low redundancy.
