| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The electroencephalogram (EEG) recording is necessary for epileptic diagnosis. In particular, the intracranial EEG (iEEG) data is essential to localize the seizure onset zone (SOZ). However, it is time-consuming and heavy load for specialists to interpret the iEEG recorded for long time. Therefore, an automatic technology to localize the SOZ is required. Based on VGG, the well-known convolutional neural network for image recognition, we propose a model for analyzing one-dimensional signals and try to localize the SOZ. For this model, the input is a signal obtained by dividing the iEEG in a short time, and the output is whether the recording area of the iEEG is the SOZ or not. Class-Balanced Focal Loss, which is reported to be effective for imbalanced data, was used as the loss function for training. We conducted time-series split cross-validation for the iEEG from cortical dysplasia epilepsy patients. As a result, the proposed model achieved generally higher AUC, F-measure, sensitivity, and specificity than the conventional method using feature extraction and SVM. In consequence, it is possible to outperform the conventional method by an appropriate neural network and loss function. | |
