CORA-Diff: Confidence-Oriented Residual Acceptance for Efficient Diffusion Language Model Inference
Yifan Wu, Yufeng Zhang, Kenli Li
Diffusion language models (DLMs) update many tokens in parallel, yet practical decoders often use a fixed denoising horizon. Many predictions stabilize early, but blockwise decodin…

Optimal Stability of KL Divergence under Gaussian Perturbations
Jialu Pan, Yufeng Zhang, Nan Hu +3
We study the problem of characterizing the stability of Kullback-Leibler (KL) divergence under Gaussian perturbations beyond Gaussian families. Existing relaxed triangle inequaliti…

Relaxed Triangle Inequality for Kullback-Leibler Divergence Between Multivariate Gaussian Distributions
Shiji Xiao, Yufeng Zhang, Chubo Liu +3
The Kullback-Leibler (KL) divergence is not a proper distance metric and does not satisfy the triangle inequality, posing theoretical challenges in certain practical applications.…
