Addressing Semantic Blind Spots in Text-to-SQL via Component Pre-generation and AST Matching Rewards

ICML 2026poster

In recent years, significant advancements in large language models have greatly propelled the development of Text-to-SQL tasks. However, due to the token-by-token sequential generation mechanism employed by these models, they encounter a semantic blind spot problem with respect to pending SQL compon…

Characterizing and Mitigating Reasoning Drift in Large Language Models

ICLR 2026poster

While chain-of-thought prompting enables powerful multi-step reasoning in Large Language Models (LLMs), the stochastic nature of the generation process undermines its reliability. In this work, we first analyze thousands of reasoning paths to identify Reasoning Drift, a key failure mode where models…

PixCLIP: Towards Fine-grained Vision-Language Understanding via Any-granularity Pixel-Text Alignment

ICML 2026poster

While CLIP has achieved strong performance across vision–language tasks, fine-grained image–text alignment remains challenging. Recent efforts improve textual granularity by leveraging long, detailed descriptions and replacing CLIP’s text encoder with LLM, but often overlook the visual-side bottlene…

Enhancing Chain of Thought Prompting in Large Language Models via Reasoning Patterns

AAAI 2025technical

Chain of Thought (CoT) prompting can encourage language models to engage in multi-step logical reasoning. The quality of the provided demonstrations significantly influences the success of downstream inference tasks. Current unsupervised CoT methods primarily select examples based on the semantics o…

PFDM: Parser-Free Virtual Try-On via Diffusion Model

ICASSP 2024accepted

Virtual try-on can significantly improve the garment shopping experiences in both online and in-store scenarios, attracting broad interest in computer vision. However, to achieve high-fidelity try-on performance, most state-of-the-art methods still rely on accurate segmentation masks, which are ofte…

TaiSu: A 166M Large-scale High-Quality Dataset for Chinese Vision-Language Pre-training

NeurIPS 2022accept

Vision-Language Pre-training (VLP) has been shown to be an efficient method to improve the performance of models on different vision-and-language downstream tasks. Substantial studies have shown that neural networks may be able to learn some general rules about language and visual concepts from a la…
