PS4: Proxy-Supervised Joint Training for Real Target Speaker Extraction
Wanyi Ning, Wei Zhou, Yingpeng Li +3
Training target speaker extraction (TSE) models for real conversational mixtures remains challenging because large-scale training corpora and clean target speech for supervision ar…
Measuring the Wrong Thing: Internal Harmfulness Scores Anti-Rank Successful Jailbreaks
Mingyu Luo, Ming Deng, Zilang Qiu +8
Internal safety scores judge a prompt before any text is generated, and they are validated by how well they separate harmful prompts from benign ones. That separation is then read…
Deep Learning Based Concurrency Bug Detection and Localization
Zuocheng Feng, Kaiwen Zhang, Miaomiao Wang +4
Concurrency bugs, caused by improper synchronization of shared resources in multi-threaded or distributed systems, are notoriously hard to detect and thus compromise software relia…
Towards Analyzing and Understanding the Limitations of VAPO: A Theoretical Perspective
Jintian Shao, Yiming Cheng
Reinforcement learning (RL) enhances large language models (LLMs) in complex, long-chain-of-thought (long-CoT) reasoning. The advanced VAPO framework, despite sophisticated mechani…
Towards Analyzing and Understanding the Limitations of VAPO: A Theoretical Perspective
Jintian Shao, Yiming Cheng, Hongyi Huang +4
The VAPO framework has demonstrated significant empirical success in enhancing the efficiency and reliability of reinforcement learning for long chain-of-thought (CoT) reasoning ta…
SearchEyes: Towards Frontier Multimodal Deep Search Intelligence via Search World Simulation
Zhengbo Jiao, Yiming Cheng, Yilei Jiang +15
Training multimodal search agents to perform multi-hop reasoning remains challenging due to a fundamental structural disconnect: existing pipelines construct training data, search…
