Beyond Perplexity: UTF-8 Validity in Byte-aware Language Models

ICML 2026poster

Byte-level tokenization enables language models to handle any Unicode input, but models can generate invalid UTF-8 sequences when encountering rare or unseen characters. We investigate the relationship between training scale and UTF-8 generation reliability with a 355M parameter model trained on 80B…

Rewriting Pre-Training Data Boosts LLM Performance in Math and Code

ICLR 2026poster

The performance of large language models (LLMs) in program synthesis and mathematical reasoning is fundamentally limited by the quality of their pre-training corpora. We introduce two openly licensed pre-training datasets, released under the Llama 3.3 Community License, that significantly enhance…

Sampling-based Pseudo-Likelihood for Membership Inference Attacks

ACL 2025finding

Large Language Models (LLMs) are trained on large-scale web data, which makes it difficult to grasp the contribution of each text. This poses the risk of leaking inappropriate data such as benchmarks, personal information, and copyrighted texts in the training data. Membership Inference Attacks (MIA…

Building a Japanese Document-Level Relation Extraction Dataset Assisted by Cross-Lingual Transfer

COLING 2024main

Document-level Relation Extraction (DocRE) is the task of extracting all semantic relationships from a document. While studies have been conducted on English DocRE, limited attention has been given to DocRE in non-English languages. This work delves into effectively utilizing existing English resour…
