Beyond Model Weights: Sampling-Dependent Fairness in Diffusion Language Models

Koshiro Saito, Daisuke Oba, Diasuke Oba +2

Diffusion language models (DLMs) are emerging as a practical alternative to autoregressive language models (ARLMs), yet their fairness remains largely uncharacterized. DLMs introdu…

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…

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

Kazuki Fujii, Yukito Tajima, Sakae Mizuki +14

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…

Building Instruction-Tuning Datasets from Human-Written Instructions with Open-Weight Large Language Models

Youmi Ma, Sakae Mizuki, Kazuki Fujii +12

Instruction tuning is crucial for enabling Large Language Models (LLMs) to solve real-world tasks. Prior work has shown the effectiveness of instruction-tuning data synthesized sol…

Why We Build Local Large Language Models: An Observational Analysis from 35 Japanese and Multilingual LLMs

Koshiro Saito, Sakae Mizuki, Masanari Ohi +11

Why do we build local large language models (LLMs)? What should a local LLM learn from the target language? Which abilities can be transferred from other languages? Do language-spe…
