Constraints-Guided Diffusion Reasoner for Neuro-Symbolic Learning

AAAI 2026technical

Enabling neural networks to learn complex logical constraints and fulfill symbolic reasoning is a critical challenge. Bridging this gap often requires guiding the neural network’s output distribution to move closer to the symbolic constraints. While diffusion models have shown remarkable generative

OpenCoder: The Open Cookbook for Top-Tier Code Large Language Models

ACL 2025long

Code LLMs have been widely used in various domains, including code generation, logical reasoning, and agent systems. However, open-access code LLMs mostly only release weights, lacking key features such as reproducible data pipelines and transparent training protocols, which are crucial for advancin…

Structure-aware Semantic Discrepancy and Consistency for 3D Medical Image Self-supervised Learning

ICCV 2025poster

3D medical image self-supervised learning (mSSL) holds great promise for medical analysis. Effectively supporting broader applications requires considering anatomical structure variations in location, scale, and morphology, which are crucial for capturing meaningful distinctions. However, previous m…

To Code or not to Code? Adaptive Tool Integration for Math Language Models via Expectation-Maximization

ACL 2025finding

Recent advances in mathematical problem-solving with language models (LMs) integrate chain-of-thought (CoT) reasoning and code execution to harness their complementary strengths. However, existing hybrid frameworks exhibit a critical limitation: they depend on externally dictated instructions or rig…

LogicMP: A Neuro-symbolic Approach for Encoding First-order Logic Constraints

ICLR 2024poster

Integrating first-order logic constraints (FOLCs) with neural networks is a crucial but challenging problem since it involves modeling intricate correlations to satisfy the constraints. This paper proposes a novel neural layer, LogicMP, which performs mean-field variational inference over a Markov L…

Extracting Trigger-sharing Events via an Event Matrix

EMNLP 2022finding

A growing interest emerges in event extraction which aims to extract multiple events with triggers and arguments. Previous methods mitigate the problem of multiple events extraction by predicting the arguments conditioned on the event trigger and event type, assuming that these arguments belong to a…
