CANDLE: Cortical Null-Space Decomposition for Noninvasive Brain Source Imaging

Shuntaro Suzuki, Yuiga Wada, Komei Sugiura

Electrophysiological source imaging (ESI) aims to estimate cortical source activity from noninvasive electrophysiological measurements such as electroencephalogram (EEG). However,…

MLLM-as-a-Judge Exhibits Model Preference Bias

Shuitsu Koyama, Yuiga Wada, Daichi Yashima +1

Automatic evaluation using multimodal large language models (MLLMs), commonly referred to as MLLM-as-a-Judge, has been widely used to measure model performance. If such MLLM-as-a-J…

LLM-Free Image Captioning Evaluation in Reference-Flexible Settings

Shinnosuke Hirano, Yuiga Wada, Kazuki Matsuda +2

We focus on the automatic evaluation of image captions in both reference-based and reference-free settings. Existing metrics based on large language models (LLMs) favor their own g…

VELA: An LLM-Hybrid-as-a-Judge Approach for Evaluating Long Image Captions

Kazuki Matsuda, Yuiga Wada, Shinnosuke Hirano +2

In this study, we focus on the automatic evaluation of long and detailed image captions generated by multimodal Large Language Models (MLLMs). Most existing automatic evaluation me…

ZINA: Multimodal Fine-grained Hallucination Detection and Editing

Yuiga Wada, Kazuki Matsuda, Komei Sugiura +1

Multimodal Large Language Models (MLLMs) often generate hallucinations, where the output deviates from the visual content. Given that these hallucinations can take diverse forms, d…

DialMAT: Dialogue-Enabled Transformer with Moment-Based Adversarial Training

Kanta Kaneda, Ryosuke Korekata, Yuiga Wada +7

This paper focuses on the DialFRED task, which is the task of embodied instruction following in a setting where an agent can actively ask questions about the task. To address this…

JaSPICE: Automatic Evaluation Metric Using Predicate-Argument Structures for Image Captioning Models

Yuiga Wada, Kanta Kaneda, Komei Sugiura

Image captioning studies heavily rely on automatic evaluation metrics such as BLEU and METEOR. However, such n-gram-based metrics have been shown to correlate poorly with human eva…

Multimodal Diffusion Segmentation Model for Object Segmentation from Manipulation Instructions

Yui Iioka, Yu Yoshida, Yuiga Wada +2

In this study, we aim to develop a model that comprehends a natural language instruction (e.g., "Go to the living room and get the nearest pillow to the radio art on the wall") and…
