On the Dimensionality and Utility of Convolutional Autoencoder’s Latent Space Trained with Topology-Preserving Spectral EEG Head-Maps

open access: yesMachine Learning and Knowledge Extraction, 2022
Electroencephalography (EEG) signals can be analyzed in the temporal, spatial, or frequency domains. Noise and artifacts during the data acquisition phase contaminate these signals adding difficulties in their analysis.

Modeling Cognitive Load as a Self-Supervised Brain Rate with Electroencephalography and Deep Learning

open access: yesBrain Sciences, 2022
The principal reason for measuring mental workload is to quantify the cognitive cost of performing tasks to predict human performance. Unfortunately, a method for assessing mental workload that has general applicability does not exist yet. This is due to

High working memory load leads to more Ebbinghaus illusion [PDF]

open access: yes, 2009
The evidence that distractor processing increases with greater load on working memory has come mainly from Stroop-type interference tasks, making it difficult to establish whether cognitive load affects distractor processing at the perceptual level or ...
