Embodiment Construction
[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0022] In order to solve the problems existing in the prior art, the present invention proposes a new urban ecological evaluation method based on the GA-BP neural network, by first determining the structure and related parameters of the BP neural network, and then utilizing the genetic algorithm to optimize the initial weight and threshold, and then input the sample data to train the BP neural network model, and finally construct the urban urban ecological evaluation model.
[0023] Such as figure 1 As shown, a flow chart of an evaluation method for urban ecological construction based on the GA-BP neural network algorithm is implemented, which includes the following steps:
[0024] Step 1: Build an evaluation index system for urban ecological evaluation;
[0025] Step 2 generates data samples for training and testing the urban urban ecolo...
