Euclean: Automated Geometry Problem Formalization with Unified Verification in Lean

ICML 2026poster

Recent formal reasoning systems achieve IMO-level performance, but create a fragmented landscape: algebra and number theory use Lean, while geometry relies on domain-specific languages with limited formal guarantees. This fragmentation increases the trusted computing base and hinders unified model d…

CAPAST: Content Affinity Preserved Arbitrary Style Transfer

ICASSP 2025accepted

Balancing the consistency of style and the integrity of content is the main challenge in arbitrary style transfer domain. Currently, local style details can be effectively captured by attention mechanism but easily produce distorted style patterns and inconsistent content structure. In this paper, w…

Multi-task Visual Grounding with Coarse-to-Fine Consistency Constraints

AAAI 2025technical

Multi-task visual grounding involves the simultaneous execution of localization and segmentation in images based on textual expressions. The majority of advanced methods predominantly focus on transformer-based multimodal fusion, aiming to extract robust multimodal representations. However, ambiguit…

Proving Olympiad Inequalities by Synergizing LLMs and Symbolic Reasoning

ICLR 2025poster

Large language models (LLMs) can prove mathematical theorems formally by generating proof steps (\textit{a.k.a.} tactics) within a proof system. However, the space of possible tactics is vast and complex, while the available training data for formal proofs is limited, posing a significant challenge…

Reviving DSP for Advanced Theorem Proving in the Era of Reasoning Models

NeurIPS 2025poster

Recent advancements, such as DeepSeek-Prover-V2-671B and Kimina-Prover-Preview-72B, demonstrate a prevailing trend in leveraging reinforcement learning (RL)-based large-scale training for automated theorem proving. Surprisingly, we discover that even without any training, careful neuro-symbolic coor…

Watch and Listen: Understanding Audio-Visual-Speech Moments with Multimodal LLM

NeurIPS 2025poster

Humans naturally understand moments in a video by integrating visual and auditory cues. For example, localizing a scene in the video like “A scientist passionately speaks on wildlife conservation as dramatic orchestral music plays, with the audience nodding and applauding” requires simultaneous proc…

Autoformalize Mathematical Statements by Symbolic Equivalence and Semantic Consistency

NeurIPS 2024poster

Autoformalization, the task of automatically translating natural language descriptions into a formal language, poses a significant challenge across various domains, especially in mathematics. Recent advancements in large language models (LLMs) have unveiled their promising capabilities to formalize…

Neuro-Symbolic Data Generation for Math Reasoning

NeurIPS 2024poster

A critical question about Large Language Models (LLMs) is whether their apparent deficiency in mathematical reasoning is inherent, or merely a result of insufficient exposure to high-quality mathematical data. To explore this, we developed an automated method for generating high-quality, supervised…
