PAR: Progress-Aligned Recurrence for Length Generalization in State Tracking

Pan Wang, Yihao Hu, Guangyuan Dong +8

Looped language models can run more iterations at test time, but additional iterations need not help them solve longer problems. For sequential state tracking, final-answer supervi…

Ask, Condition or Abstain: Reinforcement Learning for Missing-Premise Reasoning

Yongqi Tong, Zhenyu Zhang, Zimi Liu +8

Answer-only reinforcement learning (RL) trains reasoning models to solve fully specified problems, but many realistic queries omit a premise needed for a unique answer. In this set…

STAGE: Controlled Objective Admission for Multi-Preference LLM Alignment

Yongqi Tong, Zhenyu Zhang, Ruirui Wang +6

Multi-preference alignment is often framed as scalarization: combine reward dimensions, then optimize. This leaves a temporal decision underspecified: when should each preference d…

ARC: Fair Relative Advantage Comparison in Open-Ended Real-World Interaction

Yongqi Tong, Tan Li Hui Faith, Choy Zhen Wen Marcus +5

Open-ended real-world interaction admits multiple valid behaviors: an agent may answer directly, ask for clarification, provide progress updates, or confirm before acting. This fle…

Diagnosis Before Recovery: Turning Agent Failures into Selective Self-Correction

Pan Wang, Yihao Hu, Hang Wang +6

Self-correction is particularly useful when a failure constrains the next repair. Coding agents benefit from this property because compilers, tests, and execution traces turn many…

How to Train a Real-World Silicon Concierge? Internalizing Complex Business Workflow to Only OneModel

Chang Liu, Chaoyang Ning, Dayi Jiang +32

Traditional industrial agents rely on modular pipelines, including Router, Retriever, Planner, Executor, Responder, Reviewer, and other components. These systems often fracture int…

Optimal Transport for LLM Reward Modeling from Noisy Preference

Licheng Pan, Haochen Yang, Haoxuan Li +8

Reward models are fundamental to Reinforcement Learning from Human Feedback (RLHF), yet real-world datasets are inevitably corrupted by noisy preference. Conventional training obje…

Dingtalk DeepResearch: A Unified Multi Agent Framework for Adaptive Intelligence in Enterprise Environments

Mengyuan Chen, Chengjun Dai, Xinyang Dong +7

We present Dingtalk DeepResearch, a unified multi agent intelligence framework for real world enterprise environments, delivering deep research, heterogeneous table reasoning, and…

Understanding and Mitigating Overrefusal in LLMs from an Unveiling Perspective of Safety Decision Boundary

Licheng Pan, Yongqi Tong, Xin Zhang +3

Large language models (LLMs) have demonstrated remarkable capabilities across a wide range of tasks, yet they often refuse to answer legitimate queries--a phenomenon known as overr…

REWARD CONSISTENCY: Improving Multi-Objective Alignment from a Data-Centric Perspective

Zhihao Xu, Yongqi Tong, Xin Zhang +2

Multi-objective preference alignment in language models often encounters a challenging trade-off: optimizing for one human preference (e.g., helpfulness) frequently compromises oth…

BPO: Towards Balanced Preference Optimization between Knowledge Breadth and Depth in Alignment

Sizhe Wang, Yongqi Tong, Hengyuan Zhang +3

Reinforcement Learning with Human Feedback (RLHF) is the key to the success of large language models (LLMs) in recent years. In this work, we first introduce the concepts of knowle…

Optimizing Language Model's Reasoning Abilities with Weak Supervision

Yongqi Tong, Sizhe Wang, Dawei Li +6

While Large Language Models (LLMs) have demonstrated proficiency in handling complex queries, much of the past work has depended on extensively annotated datasets by human experts.…

Can LLMs Learn from Previous Mistakes? Investigating LLMs' Errors to Boost for Reasoning

Yongqi Tong, Dawei Li, Sizhe Wang +3

Recent works have shown the benefits to LLMs from fine-tuning golden-standard Chain-of-Thought (CoT) rationales or using them as correct examples in few-shot prompting. While human…

Eliminating Reasoning via Inferring with Planning: A New Framework to Guide LLMs' Non-linear Thinking

Yongqi Tong, Yifan Wang, Dawei Li +4

Chain-of-Thought(CoT) prompting and its variants explore equipping large language models (LLMs) with high-level reasoning abilities by emulating human-like linear cognition and log…

ToxicChat: Unveiling Hidden Challenges of Toxicity Detection in Real-World User-AI Conversation

Zi Lin, Zihan Wang, Yongqi Tong +4

Despite remarkable advances that large language models have achieved in chatbots, maintaining a non-toxic user-AI interactive environment has become increasingly critical nowadays.…

Pretrained Language Encoders are Natural Tagging Frameworks for Aspect Sentiment Triplet Extraction

Yanjie Gou, Yinjie Lei, Lingqiao Liu +3

Aspect Sentiment Triplet Extraction (ASTE) aims to extract the spans of aspect, opinion, and their sentiment relations as sentiment triplets. Existing works usually formulate the s…
