As a result of Wilcoxon test with six evaluation cases, it was confirmed that the feature value that makes it easy to distinguish between the two types differs for each evaluation case. In addition, in the evaluation of the correct answer rate using machine learning, when we generated classifiers for 16 experiment participants, we recorded a maximum correct answer rate of 71% (+21% from the chance level), and we also confirmed the superiority of using multiple feature values generated from θ, α, and β waves at the same time.}, title = {特徴が異なるプレゼンテーション動画視聴時の脳活動比較-トピックの難易度と説明の上手さを指標とした評価-}, year = {2023} }
