| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Estimating perceived music from intracranial electroencephalogram measured with implanted electrodes is challenging. In this study, we recorded stereo electroencephalogram (SEEG) during music perception and attempted to estimate the log-mel spectrogram of short melodies, approximately 4 seconds in duration. The mean squared error (MSE) loss was calculated from the estimated log-mel spectrogram and ground truth labels, and the results were compared with those obtained when the input was a random signal. The results of a two-way analysis of variance revealed a significant reduction in MSE loss compared to chance level. However, no significant differences were observed for the encoder type or interaction. Furthermore, reconstruction of the acoustic signal from the estimated log-mel spectrogram with low MSE allowed for subjective recognition of the heard melody. | |
