Beyond Text-to-SQL: Can LLMs Really Debug Enterprise ETL SQL?

ICML 2026poster

SQL is central to enterprise data engineering, yet generating fully correct SQL code in a single attempt remains difficult—even for experienced developers and advanced \ttsql LLMs—often requiring multiple debugging iterations. We introduce \textbf{\ourbench}, the first benchmark for enterprise-level…

BiEvLight: Bi-level Learning of Task-Aware Event Refinement for Low-Light Image Enhancement

CVPR 2026

Event cameras, with their high dynamic range, show great promise for Low-light Image Enhancement (LLIE). Existing works primarily focus on designing effective modal fusion strategies. However, a key challenge is the dual degradation from intrinsic background activity (BA) noise in events and low sig

Bridging Optimization and Neural Networks for Efficient Multi-view Clustering

AAAI 2026technical

Multi-view clustering (MVC) seeks to uncover the intrinsic group structures embedded in multi-view data, which has attracted considerable attention in recent years. Existing approaches predominantly concentrate on incorporating suitable model priors to capture consistency across views. However, thes

Chart Deep Research in LVLMs via Parallel Relative Policy Optimization

ICLR 2026poster

With the rapid advancement of data science, charts have evolved from simple numerical presentation tools to essential instruments for insight discovery and decision-making support. However, current chart data intelligence exhibits significant limitations in deep research capabilities, with existing…

SRJudge: Empowering Large Language Models with Selective Reasoning for Fine-Grained Knowledge Concept Tagging

IJCAI 2026

Knowledge concept tagging aims to assign specific concept or topic labels to educational content, which is essential for both educators and learners in traditional and online teaching practices. Recent work has explored large language models (LLMs) for this task, achieving promising performance. How

Graph-Reward-SQL: Execution-Free Reinforcement Learning for Text-to-SQL via Graph Matching and Stepwise Reward

EMNLP 2025

Reinforcement learning (RL) has been widely adopted to enhance the performance of large language models (LLMs) on Text-to-SQL tasks. However, existing methods often rely on execution-based or LLM-based Bradley–Terry reward models. The former suffers from high execution latency caused by repeated dat

Integrating Multi-Scale Compression Attention with Edge Detection for Ultrasound Tumor Segmentation

ICASSP 2025accepted

Tumor segmentation is particularly important for ultrasound imaging-based diagnosis and therapy, such as breast cancer and gastrointestinal stromal tumor. However, the accurate ultrasound tumor segmentation remains challenging due to insufficient textures and edge features resulted from limited reso…

EMGAN: Early-Mix-GAN on Extracting Server-Side Model in Split Federated Learning

AAAI 2024technical

Split Federated Learning (SFL) is an emerging edge-friendly version of Federated Learning (FL), where clients process a small portion of the entire model. While SFL was considered to be resistant to Model Extraction Attack (MEA) by design, a recent work shows it is not necessarily the case. In gener…

Enhancing Ontology Translation Through Cross-Lingual Agreement

ICASSP 2023accepted

Ontology serves as the foundation for the underlying representation of knowledge. In order to achieve the sharing of knowledge across languages, ontologies that are typically only represented in English must be translated into different languages. Building a domain-specific translation system is nec…

The Sufficiency of Off-Policyness and Soft Clipping: PPO Is Still Insufficient according to an Off-Policy Measure

AAAI 2023technical

The popular Proximal Policy Optimization (PPO) algorithm approximates the solution in a clipped policy space. Does there exist better policies outside of this space? By using a novel surrogate objective that employs the sigmoid function (which provides an interesting way of exploration), we found th…

ResSFL: A Resistance Transfer Framework for Defending Model Inversion Attack in Split Federated Learning

CVPR 2022poster

This work aims to tackle Model Inversion (MI) attack on Split Federated Learning (SFL). SFL is a recent distributed training scheme where multiple clients send intermediate activations (i.e., feature map), instead of raw data, to a central server. While such a scheme helps reduce the computational l…
