    　View Summary

    As the influence of AI continues to expand across diverse sectors, the need for a practical ethical framework to prevent biases and guide responsible applications becomes increasingly paramount. This study proposes an innovative educational approach that combines the Case Method with network analysis to examine ethical challenges in AI. To evaluate the framework’s capacity for analyzing response patterns and enhancing ethical decision-making, we conduct a comprehensive case study focusing on the use of AI in Japanese job-hunting practices. Analyzing participant responses before and after targeted educational interventions reveals notable improvements in ethical reasoning and awareness, thereby underscoring the framework’s effectiveness in fostering critical ethical engagement.

    IEICE Transactions on Information and Systems (Web)   E107.D ( 8 ) 1059 - 1069  2024

    　View Summary

    Makeup transfer is the process of applying the makeup style from one picture (reference) to another (source), allowing for the modification of characters' makeup styles. To meet the diverse makeup needs of individuals or samples, the makeup transfer framework should accurately handle various makeup degrees, ranging from subtle to bold, and exhibit intelligence in adapting to the source makeup. This paper introduces a “3-level” adaptive makeup transfer framework, addressing facial makeup through two sub-tasks: 1. Makeup adaptation, utilizing feature descriptors and eyelid curve algorithms to classify 135 organ-level face shapes; 2. Makeup transfer, achieved by learning the reference picture from three branches (color, highlight, pattern) and applying it to the source picture. The proposed framework, termed “Face Shape Adaptive Makeup Transfer” (FSAMT), demonstrates superior results in makeup transfer output quality, as confirmed by experimental results.

  • A Hypergraph Motif Analysis Method for Understanding Structures in Consumer Evaluations

    2025   Goto Masayuki, Yuya Ieiri, Xu Wang

    　View Summary

    This research successfully developed a hypergraph motif analysis method to decode complex, non-linear structures in consumer evaluations. Unlike traditional pairwise analysis, our approach captures high-order interactions among consumers, products, and sentiments.The project yielded three core contributions:Methodological Innovation: Established a robust framework utilizing network motifs to model time-series dynamics and multi-dimensional consumer feedback.Empirical Validation: The method was successfully applied to diverse real-world datasets, validating its effectiveness across second-hand luxury e-commerce, commercial district marketing (stamp rally data), and AI ethics education.Market Insight Generation: The analysis revealed critical structural patterns, including dynamic sentiment dependencies and distinct behavioral differences between e-commerce and brick-and-mortar luxury markets.These findings provide granular, actionable insights for data-driven marketing strategies. The project outcomes have been widely disseminated, resulting in three peer-reviewed journal articles (including Decision Analytics Journal and Journal of Information Processing) and one international conference proceeding in 2025.
