EvolProver: Advancing Automated theorem proving by Evolving Formalized Problems via Symmetry and Difficulty

ICLR 2026poster

Large Language Models (LLMs) for formal theorem proving have shown significant promise, yet they often lack generalizability and are fragile to even minor transformations of problem statements. To address this limitation, we introduce a novel data augmentation pipeline designed to enhance model robu…

Full-Graph vs. Mini-Batch Training: Comprehensive Analysis from a Batch Size and Fan-Out Size Perspective

ICLR 2026poster

Full-graph and mini-batch Graph Neural Network (GNN) training approaches have distinct system design demands, making it crucial to choose the appropriate approach to develop. A core challenge in comparing these two GNN training approaches lies in characterizing their model performance (i.e., converg…

Hierarchy Decoding: A Training-free Parallel Decoding Strategy for Diffusion Large Language Models

ICLR 2026poster

The utilization of large language models (LLMs) has become increasingly widespread, and has attracted considerable attention. Although the emergence of discrete diffusion large language models (dLLMs) mitigates the inference latency inherent in autoregressive LLM decoding, its computational overhead…

Why Do Open-Source LLMs Struggle with Data Analysis? A Systematic Empirical Study

AAAI 2026technical

Large Language Models (LLMs) hold promise in automating data analysis tasks, yet open-source models face significant limitations in these kinds of reasoning-intensive scenarios. In this work, we investigate strategies to enhance the data analysis capabilities of open-source LLMs. By curating a seed

LightThinker: Thinking Step-by-Step Compression

EMNLP 2025

Large language models (LLMs) have shown remarkable performance in complex reasoning tasks, but their efficiency is hindered by the substantial memory and computational costs associated with generating lengthy tokens. In this paper, we propose LightThinker, a novel method that enables LLMs to dynamic

Untie the Knots: An Efficient Data Augmentation Strategy for Long-Context Pre-Training in Language Models

ACL 2025long

Large language models (LLM) have prioritized expanding the context window from which models can incorporate more information. However, training models to handle long contexts presents significant challenges. These include the scarcity of high-quality natural long-context data, the potential for perf…

NetInfoF Framework: Measuring and Exploiting Network Usable Information

ICLR 2024spotlight

Given a node-attributed graph, and a graph task (link prediction or node classification), can we tell if a graph neural network (GNN) will perform well? More specifically, do the graph structure and the node features carry enough usable information for the task? Our goals are (1) to develop a fast t…
