Autoregressive Direct Preference Optimization

Masanari Oi, Mahiro Ukai, Masahiro Kaneko +2

Direct preference optimization (DPO) has emerged as a promising approach for aligning large language models (LLMs) with human preferences. However, the widespread reliance on the r…

Stopping Computation for Converged Tokens in Masked Diffusion-LM Decoding

Daisuke Oba, Danushka Bollegala, Masahiro Kaneko +1

Masked Diffusion Language Models generate sequences via iterative sampling that progressively unmasks tokens. However, they still recompute the attention and feed-forward blocks fo…

Multi-modal, Multi-task, Multi-criteria Automatic Evaluation with Vision Language Models

Masanari Ohi, Masahiro Kaneko, Naoaki Okazaki +1

Vision-language models (VLMs) have shown impressive abilities across a range of multi-modal tasks. However, existing metrics for evaluating the quality of text generated by VLMs ty…

Likelihood-based Mitigation of Evaluation Bias in Large Language Models

Masanari Oi, Masahiro Kaneko, Ryuto Koike +2

Large Language Models (LLMs) are widely used to evaluate natural language generation tasks as automated metrics. However, the likelihood, a measure of LLM's plausibility for a sent…

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…

How You Prompt Matters! Even Task-Oriented Constraints in Instructions Affect LLM-Generated Text Detection

Ryuto Koike, Masahiro Kaneko, Naoaki Okazaki

To combat the misuse of Large Language Models (LLMs), many recent studies have presented LLM-generated-text detectors with promising performance. When users instruct LLMs to genera…
