Characterizing Agents in Production

ICML 2026oral

LLM-based agents already operate in production across many industries, yet we lack a clear understanding of which technical methods make these deployments successful. We present the first systematic study of Characterizing Agents in Production (CAP) using first-hand data from agent developers. We co…

IO-RAE: Information-Obfuscation Reversible Adversarial Example for Audio Privacy Protection

AAAI 2026technical

The rapid advancements in artificial intelligence have significantly accelerated the adoption of speech recognition technology, leading to its widespread integration across various applications. However, this surge in usage also highlights a critical issue: audio data is highly vulnerable to unautho

Position: Agent Evaluation Should Be Agentified for Openness, Standardization, and Reproducibility

ICML 2026poster

Agent systems are advancing quickly across domains, but their evaluation remains fragmented. Most benchmarks rely on fixed, LLM-centric harnesses that require heavy integration, create test-production mismatch, and limit fair comparison across diverse agent designs. This position paper argues that t…

The Pensieve Paradigm: Stateful Language Models with Learned Memory Management

ICLR 2026poster

In the world of Harry Potter, when Dumbledore's mind is overburdened, he extracts memories into a Pensieve to be revisited later. In the world of AI, while we possess the Pensieve—mature databases and retrieval systems, our models inexplicably lack the "wand" to operate it. They remain like a Dumble…

AI Sees Your Location—But With A Bias Toward The Wealthy World

EMNLP 2025

Visual-Language Models (VLMs) have shown remarkable performance across various tasks, particularly in recognizing geographic information from images. However, VLMs still show regional biases in this task. To systematically evaluate these issues, we introduce a benchmark consisting of 1,200 images pa

Can’t See the Forest for the Trees: Benchmarking Multimodal Safety Awareness for Multimodal LLMs

ACL 2025long

Multimodal Large Language Models (MLLMs) have expanded the capabilities of traditional language models by enabling interaction through both text and images. However, ensuring the safety of these models remains a significant challenge, particularly in accurately identifying whether multimodal content…

Insight Over Sight: Exploring the Vision-Knowledge Conflicts in Multimodal LLMs

ACL 2025long

This paper explores the problem of commonsense level vision-knowledge conflict in Multimodal Large Language Models (MLLMs), where visual information contradicts model’s internal commonsense knowledge. To study this issue, we introduce an automated framework, augmented with human-in-the-loop quality…

MetaScope: Optics-Driven Neural Network for Ultra-Micro Metalens Endoscopy

ICCV 2025poster

Miniaturized endoscopy has advanced accurate visual perception within the human body. Prevailing research remains limited to conventional cameras employing convex lenses, where the physical constraints with millimetre-scale thickness impose serious impediments on the micro-level clinical. Recently,…

The First Few Tokens Are All You Need: An Efficient and Effective Unsupervised Prefix Fine-Tuning Method for Reasoning Models

NeurIPS 2025poster

Improving the reasoning capabilities of large language models (LLMs) typically requires supervised fine-tuning with labeled data or computationally expensive sampling. We introduce Unsupervised Prefix Fine-Tuning (UPFT), which leverages the observation of Prefix Self-Consistency -- the shared initia…

Trust, But Verify: A Self-Verification Approach to Reinforcement Learning with Verifiable Rewards

NeurIPS 2025poster

Large Language Models (LLMs) show great promise in complex reasoning, with Reinforcement Learning with Verifiable Rewards (RLVR) being a key enhancement strategy. However, a prevalent issue is ``superficial self-reflection'', where models fail to robustly verify their own outputs. We introduce RISE…

Effective and Efficient Federated Tree Learning on Hybrid Data

ICLR 2024poster

Federated learning has emerged as a promising distributed learning paradigm that facilitates collaborative learning among multiple parties without transferring raw data. However, most existing federated learning studies focus on either horizontal or vertical data settings, where the data of differen…

Predicate Debiasing in Vision-Language Models Integration for Scene Graph Generation Enhancement

EMNLP 2024main

Scene Graph Generation (SGG) provides basic language representation of visual scenes, requiring models to grasp complex and diverse semantics between objects. This complexity and diversity in SGG leads to underrepresentation, where parts of triplet labels are rare or even unseen during training, res…

Sentence-aware Adversarial Meta-Learning for Few-Shot Text Classification

COLING 2022main

Meta-learning has emerged as an effective approach for few-shot text classification. However, current studies fail to realize the importance of the semantic interaction between sentence features and neglect to enhance the generalization ability of the model to new tasks. In this paper, we integrate…
