Embodiment Construction
[0113] The present invention is further described above in conjunction with the accompanying drawings and specific embodiments.
[0114] (1) Select the feature quantities related to the fatigue driving state: feature selection refers to a feature set composed of a group of related feature quantities obtained after a series of corresponding processing on the original measurement signal, and then select some features from the feature set. The representative physical quantity with the best classification performance is used as a set of feature quantities to distinguish different behaviors, and then the relevant classification recognition method is used to separate different behaviors from the feature space by using the selected feature quantities. Therefore, for learning classification Both require training set samples:
[0115] T={(x 1 ,y 1 ),..., (x 1 ,y 1 )}∈(X×Y) 1 (1)
[0116] where x i ∈X=R n ,y i ∈Y=R, i=1,...,1;
[0117] For the training set that meets the requ...
