Embodiment Construction
[0040] according to figure 1 , figure 2 As shown, a mine shaft engineering surrounding rock artificial intelligence classification method includes:
[0041] (1) Establishing a neural network model
[0042] The establishment of the neural network model is to determine the main factors that affect the stability of the surrounding rock, and determine the input and output information of the network model according to the main factors, and then establish the model structure and algorithm based on this.
[0043] Determine eight input variables and one output variable, and the established BP neural network model can be regarded as a highly nonlinear mapping from input to output, namely: R8→R1. input(x i ∈R8) and output (y i ∈R1), the BP neural network structure is as attached to the instruction figure 1 shown.
[0044] The number of neurons in the first layer is determined to be 18.
[0045] The number of neurons in the second hidden layer should be one-third of the first lay...
