Multimodal Autoencoder Predicts fNIRS Resting State From EEG Signals

Abstract: In this work, we introduce a deep learning architecture for evaluation on multimodal electroencephalographic (EEG) and functional near-infrared spectroscopy (fNIRS) recordings from 40 epileptic patients. Long short-term memory units and convolutional neural networks are integrated within a multimodal sequence-to-sequence autoencoder. The trained neural network predicts fNIRS signals from EEG, sans a priori, by hierarchically extracting deep features from EEG full spectra and specific EEG frequency bands. Resul… Show more

“…Combining fNIRS with EEG is beneficial, since EEG can measure neuronal activity at a high temporal resolution for microstate analysis. In contrast, fNIRS can uncover cortical correlates of microstates under the neurovascular coupling phenomenon [49,88,90]. Microstate prototypes were selected from the excellent temporal resolution of EEG [64] and the meta-criterion for global field power (GFP) [16].…”

“…7 , with the CNN achieving an area under the curve (AUC) of the receiver operating characteristic curve (ROC curve) of 0.92, which outperformed the ANN, ICA, and seed-based methods with each reporting an AUC of 0.89, 0.88, and 0.79, respectively. Another study that investigated RSFC, Sirpal et al., 85 collected EEG and fNIRS data and attempted to use the EEG data and an LSTM to recreate the fNIRS signals. Using only the gamma bands of the EEG signal was found to have the lowest reconstruction error, below 0.25.…”

“…This helps an MAE [45,47,48] to learn from the prior distribution flexibly by capturing features from a target distribution. Therefore, MAE-based approaches have been applied in a variety of settings such as natural language understanding (e.g., document and dialogue modeling) [45], emotion recognition [47], and near-infrared spectroscopy resting state prediction from multimodal electroencephalographic signals [49]. Besides, to make the most of multimodal data, a large amount of literature is devoted to the construction of integration methods for predicting cancer survival [48].…”
