J106-A(3) 104-113, Mar 1, 2023 Peer-reviewedBased on the behavior analysis of the co-eating of older adults, this study clarifies the effects of psychological health on meal time conversation. We conducted a dietary experiment in which the same menu was provided in individual and platter formats to four groups consisting of six older adults. From the recorded video, participant's speech behaviors were annotated from the start of eating to 20 minutes. The subjects of analysis were the amount of speech and topics of the participants. The results revealed that during the meal, the speaker could easily secure a situation in which they continued to speak at a certain time, and the participants activated the interaction on the topic of cooking. This study found that co-eating conversation functions as a place to deepen mutual understanding among participants and to give the first meeting an opportunity to talk with each other.

Proceedings of the Annual Conference of JSAI, JSAI2021 4G3GS2l01-4G3GS2l01, 2021Knowledge acquisition from graph structured data is an important task in machine learning and data mining. TTSP (Two-Terminal Series Parallel) graphs are used as data models for electric networks and scheduling. We propose an evolutionary learning method for obtaining characteristic multiple TTSP graph patterns with wildcards, from positive and negative TTSP graph data by clustering TTSP graphs.

Proceedings of the Annual Conference of JSAI, JSAI2021 4G3GS2l02-4G3GS2l02, 2021Machine learning and data mining from tree structured data are studied intensively. We propose an evolutionary learning method for acquiring characteristic tag tree patterns with vertex labels and wildcards from positive and negative tree data, by using label information of positive examples. We report preliminary experimental results on our evolutionary learning method.

Proceedings of the Annual Conference of JSAI, JSAI2020 1O3GS802-1O3GS802, 2020Machine learning from graph structured data are studied intensively. Many chemical compounds can be expressed by outerplanar graphs. The purpose of this paper is to propose a learning method for obtaining characteristic graph patterns from positive and negative outerplanar graph data. We propose a two-stage evolutionary learning method for acquiring characteristic multiple block preserving outerplanar graph patterns with wildcards from positive and negative outerplanar graph data, by using label information of positive examples. We report preliminary experimental results on our evolutionary learning method.
