Learning Rules, Memorizing Facts: An Information-Theoretic View of Hallucination

Gengze Xu, Anxin Guo, Yifei Hu +3

Understanding the relationship between generalization and hallucination requires clarifying the role of memorization. We study this relationship from an information-theoretic persp…

DeepSeek-V4.1-Flash: Pushing the Limits of KV Cache Compression

DeepSeek-AI, :, Anyi Xu +585

The widespread adoption of long-horizon agents has made model workloads increasingly input-heavy. Although prior work has substantially reduced the cost of long-context computation…

Beyond Penalization: Diffusion-based Out-of-Distribution Detection and Selective Regularization in Offline Reinforcement Learning

Qingjun Wang, Hongtu Zhou, Hang Yu +5

Offline reinforcement learning (RL) faces a critical challenge of overestimating the value of out-of-distribution (OOD) actions. Existing methods mitigate this issue by penalizing…

Neural-Driven Image Editing

Pengfei Zhou, Jie Xia, Xiaopeng Peng +15

Traditional image editing typically relies on manual prompting, making it labor-intensive and inaccessible to individuals with limited motor control or language abilities. Leveragi…

On Weak-to-Strong Generalization and f-Divergence

Wei Yao, Gengze Xu, Huayi Tang +4

Weak-to-strong generalization (W2SG) has emerged as a promising paradigm for stimulating the capabilities of strong pre-trained models by leveraging supervision from weaker supervi…

Weak-to-Strong Generalization via Bregman Bias-Variance Decomposition

Gengze Xu, Wei Yao, Ziqiao Wang +1

Weak-to-strong generalization (W2SG) is the phenomenon in which a powerful student model, trained on labels produced by a weaker teacher, ultimately outperforms the teacher on the…

Ensemble Debiasing Across Class and Sample Levels for Fairer Prompting Accuracy

Ruixi Lin, Ziqiao Wang, Yang You

Language models are strong few-shot learners and achieve good overall accuracy in text classification tasks, masking the fact that their results suffer from great class accuracy im…

MutualVPR: A Mutual Learning Framework for Resolving Supervision Inconsistencies via Adaptive Clustering

Qiwen Gu, Xufei Wang, Junqiao Zhao +4

Visual Place Recognition (VPR) enables robust localization through image retrieval based on learned descriptors. However, drastic appearance variations of images at the same place…
