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

Sangwhan Moon, Daisuke Oba, Youmi Ma +2

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 investi…

From Interpretability to Performance: Optimizing Retrieval Heads for Long-Context Language Models

Youmi Ma, Naoaki Okazaki

Advances in mechanistic interpretability have identified special attention heads, known as retrieval heads, that are responsible for retrieving information from the context. Howeve…

Machine Text Detectors are Membership Inference Attacks

Ryuto Koike, Liam Dugan, Masahiro Kaneko +2

Although membership inference attacks (MIAs) and machine-generated text detection target different goals, their methods often exploit similar signals based on a language model's pr…

Intent-Aware Self-Correction for Mitigating Social Biases in Large Language Models

Panatchakorn Anantaprayoon, Masahiro Kaneko, Naoaki Okazaki

Self-Correction based on feedback improves the output quality of Large Language Models (LLMs). Moreover, as Self-Correction functions like the slow and conscious System-2 thinking…

ExaGPT: Example-Based Machine-Generated Text Detection for Human Interpretability

Ryuto Koike, Masahiro Kaneko, Ayana Niwa +2

Detecting texts generated by Large Language Models (LLMs) could cause grave mistakes due to incorrect decisions, such as undermining students' academic dignity. LLM text detection…
