Unnatural Languages Are Not Bugs but Features for LLMs

ICML 2025poster

Large Language Models (LLMs) have been observed to process non-human-readable text sequences, such as jailbreak prompts, often viewed as a bug for aligned LLMs. In this work, we present a systematic investigation challenging this perception, demonstrating that unnatural languages - strings that appe…

A Comprehensive Study on Large-Scale Graph Training: Benchmarking and Rethinking

NeurIPS 2022accept

Large-scale graph training is a notoriously challenging problem for graph neural networks (GNNs). Due to the nature of evolving graph structures into the training process, vanilla GNNs usually fail to scale up, limited by the GPU memory space. Up to now, though numerous scalable GNN architectures ha…
