Beyond Hard Writes and Rigid Preservation: Soft Recursive Least-Squares for Lifelong LLM Editing

IJCAI 2026

Model editing updates a pre-trained LLM with new facts or rules without retraining while preserving unrelated behavior. In real deployment, edits arrive as long streams, creating a plasticity–stability dilemma: repeated locate-then-edit “hard writes” can accumulate interference over time, while rigi

Improving Context Fidelity via Native Retrieval-Augmented Reasoning

EMNLP 2025

Large language models (LLMs) often struggle with context fidelity, producing inconsistent answers when responding to questions based on provided information. Existing approaches either rely on expensive supervised fine-tuning to generate evidence post-answer or train models to perform web searches w

When Do Graph Neural Networks Help with Node Classification? Investigating the Homophily Principle on Node Distinguishability

NeurIPS 2023poster

Homophily principle, i.e., nodes with the same labels are more likely to be connected, has been believed to be the main reason for the performance superiority of Graph Neural Networks (GNNs) over Neural Networks on node classification tasks. Recent research suggests that, even in the absence of homo…

Revisiting Heterophily For Graph Neural Networks

NeurIPS 2022accept

Graph Neural Networks (GNNs) extend basic Neural Networks (NNs) by using graph structures based on the relational inductive bias (homophily assumption). While GNNs have been commonly believed to outperform NNs in real-world tasks, recent work has identified a non-trivial set of datasets where their…

Break the Ceiling: Stronger Multi-scale Deep Graph Convolutional Networks

NeurIPS 2019poster

Recently, neural network based approaches have achieved significant progress for solving large, complex, graph-structured problems. Nevertheless, the advantages of multi-scale information and deep architectures have not been sufficiently exploited. In this paper, we first analyze key factors constra…
