Embodiment
[0060] The modeling method of the pilot working state identification model provided in this embodiment includes the following steps:
[0061] Step S1: Preprocessing the flight data
[0062] Step S2: performing feature extraction on the preprocessed flight data;
[0063] Step S3: Using the Treelets algorithm to perform data dimensionality reduction on the extracted features;
[0064] Step S4: Classify the feature data after dimensionality reduction by using a Gaussian process classifier optimized based on the cuckoo algorithm (training modeling);
[0065] Further, in step S1, a total of 11 items including longitudinal acceleration, lateral acceleration, vertical acceleration, pitch angle, yaw angle, roll angle, ground speed, pitch rate, yaw rate, roll rate and attack angle are selected from the flight data. flight parameters, and normalize the flight parameters to obtain the flight parameter data set; the flight parameter data set is calibrated with two types, namely {+1, -1}...
