In this paper we introduce a cross-subject workload classier based on a hierarchical Bayes Model. The cross-subject classier is trained and tested with data from a group of subjects. In our work, it was trained and tested on EEG data collected from 8 subjects as they performed the Multi-Attribute Task Battery across three levels of difficulty. The accuracy of this cross-subject classier is stable across the three levels of workload and comparable to a benchmark subject-specific neural network classier.},

Most of the current EEG-based workload classiers are subject-specific; that is, a new classier is built and trained for each human subject. In this paper we introduce a cross-subject workload classier based on a hierarchical Bayes Model. The cross-subject classier is trained and tested with data from a group of subjects. In our work, it was trained and tested on EEG data collected from 8 subjects as they performed the Multi-Attribute Task Battery across three levels of difficulty. The accuracy of this cross-subject classier is stable across the three levels of workload and comparable to a benchmark subject-specific neural network classier.
