We have machine learning and crew state experience and expertise. We pioneered the study and use of real-time-compatible methods ten years ago. The best thus far used autoencoding to deal with biological noise, and two 6-layer dense neural networks. Non-nominal attentional states are identified at a rates > 0.8.
