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…
Neuron Level Analysis of Large Language Model in Legal Domain Reasoning
Eri Onami, Youmi Ma, Shuhei Kurita +1
We presented a neuron-level analysis of legal-domain reasoning in LLMs, comparing it with other applied domain tasks across seven open-weight models. Using neuron attribution score…
Drifting Objectives for Refining Discrete Diffusion Language Models
Daisuke Oba, Hiroki Furuta, Naoaki Okazaki
Discrete diffusion language models (DDLMs) generate text by iteratively denoising categorical token sequences, while recent drifting methods for continuous generators suggest that…
LLM Output Detectability and Task Performance Can be Jointly Optimized
Koshiro Saito, Ryuto Koike, Masahiro Kaneko +1
Detecting machine-generated text is essential for transparency and accountability when deploying LLMs. Watermarking enables statistically reliable detection by biasing token distri…
Synthesizing Instruction-Tuning Datasets with Contrastive Decoding
Tatsuya Ichinose, Youmi Ma, Masanari Oi +2
Using responses generated by high-performing large language models (LLMs) for instruction tuning has become a widely adopted approach. However, the existing literature overlooks a…
Aligning Tree-Search Policies with Fixed Token Budgets in Test-Time Scaling of LLMs
Sora Miyamoto, Daisuke Oba, Naoaki Okazaki
Tree-search decoding is an effective form of test-time scaling for large language models (LLMs), but real-world deployment often imposes a fixed per-query token budget that varies…
