Session-independent EEG-based Workload Recognition

Abstract

In this paper, we investigate the development of a session-independent EEG-based workload recognition system with minimal calibration time. On a corpus of ten sessions with the same subject, we investigate three different approaches: Accumulation of training data, an adaptive classifier (adaptive LDA) and feature selection algorithm (based on Mutual Information) to improve generalizability of the classifier. In a detailed evalution, we investigate how each approach performs under different conditions and show how we can use those methods to improve classification accuracy by more than 22% and make transfer of models between sessions more reliable.
