Compress-then-Rank: Faster and Better Listwise Reranking with Large Language Models via Ranking-Aware Passage Compression

AAAI 2026technical

Listwise reranking with Large Language Models (LLMs) has emerged as the state-of-the-art approach, consistently establishing new performance benchmarks in passage reranking. However, their practical application faces two critical hurdles: the prohibitive computational overhead and high latency of pr

Evoking User Memory: Personalizing LLM via Recollection-Familiarity Adaptive Retrieval

ICLR 2026poster

Personalized large language models (LLMs) rely on memory retrieval to incorporate user-specific histories, preferences, and contexts. Existing approaches either overload the LLM by feeding all the user's past memory into the prompt, which is costly and unscalable, or simplify retrieval into a one-sh…

From Single to Multi-Granularity: Toward Long-Term Memory Association and Selection of Conversational Agents

ICLR 2026poster

Large Language Models (LLMs) have recently been widely adopted in conversational agents. However, the increasingly long interactions between users and agents accumulate extensive dialogue records, making it difficult for LLMs with limited context windows to maintain a coherent long-term dialogue mem…

Personalize Before Retrieve: LLM-based Personalized Query Expansion for User-Centric Retrieval

AAAI 2026technical

Retrieval-Augmented Generation (RAG) critically depends on effective query expansion to retrieve relevant information. However, existing expansion methods adopt uniform strategies that overlook user-specific semantics, ignoring individual expression styles, preferences, and historical context. In pr

Towards Pareto-Optimal Tool-Integrated Agents with Pareto Ranking Policy Optimization

ICML 2026spotlight

Recent advances in tool-integrated language agents have significantly improved their ability to solve complex reasoning tasks. However, existing alignment methods predominantly focus on maximizing task accuracy, while overlooking auxiliary objectives such as tool-use efficiency, which are essential …

Boosting Multi-modal Keyphrase Prediction with Dynamic Chain-of-Thought in Vision-Language Models

EMNLP 2025

Multi-modal keyphrase prediction (MMKP) aims to advance beyond text-only methods by incorporating multiple modalities of input information to produce a set of conclusive phrases. Traditional multi-modal approaches have been proven to have significant limitations in handling the challenging absence a

Process vs. Outcome Reward: Which is Better for Agentic RAG Reinforcement Learning

NeurIPS 2025poster

Retrieval-augmented generation (RAG) enhances large language models (LLMs) by integrating external knowledge, yet traditional RAG systems struggle with static workflows and limited adaptability for complex, multistep reasoning tasks. Agentic RAG systems, such as DeepResearch, address these issues th…

SciNLP: A Domain-Specific Benchmark for Full-Text Scientific Entity and Relation Extraction in NLP

EMNLP 2025

Structured information extraction from scientific literature is crucial for capturing core concepts and emerging trends in specialized fields. While existing datasets aid model development, most focus on specific publication sections due to domain complexity and the high cost of annotating scientifi

DFD: Distilling the Feature Disparity Differently for Detectors

ICML 2024poster

Knowledge distillation is a widely adopted model compression technique that has been successfully applied to object detection. In feature distillation, it is common practice for the student model to imitate the feature responses of the teacher model, with the underlying objective of improving its ow…

SDPose: Tokenized Pose Estimation via Circulation-Guide Self-Distillation

CVPR 2024poster

Recently transformer-based methods have achieved state-of-the-art prediction quality on human pose estimation(HPE). Nonetheless most of these top-performing transformer-based models are too computation-consuming and storage-demanding to deploy on edge computing platforms. Those transformer-based mod…

DistilPose: Tokenized Pose Regression With Heatmap Distillation

CVPR 2023poster

In the field of human pose estimation, regression-based methods have been dominated in terms of speed, while heatmap-based methods are far ahead in terms of performance. How to take advantage of both schemes remains a challenging problem. In this paper, we propose a novel human pose estimation frame…

RPG-Palm: Realistic Pseudo-data Generation for Palmprint Recognition

ICCV 2023poster

Palmprint recently shows great potential in recognition applications as it is a privacy-friendly and stable biometric. However, the lack of large-scale public palmprint datasets limits further research and development of palmprint recognition. In this paper, we propose a novel realistic pseudo-palmp…

BézierPalm: A Free Lunch for Palmprint Recognition

ECCV 2022poster

"Palmprints are private and stable information for biometric recognition. In the deep learning era, the development of palmprint recognition is limited by the lack of sufficient training data. In this paper, by observing that palmar creases are the key information to deep-learning-based palmprint re…
