The study aims to classify mental workload levels in air traffic control using psychophysiological data and machine learning classifiers.
Two classifiers were tested: artificial neural networks and stepwise discriminant classifiers.
Data from 7 air traffic controllers were used for training and testing.
Saliency analysis was applied for feature reduction.
Classification accuracy ranged from 84% to 88% between task difficulty manipulations.
Feature reduction led to a mean of 90% correct classification accuracy with artificial neural networks.
When framed as a 2-class problem, the mean percentage correct classification was 98% for acceptable load versus overload.
