Web5 jan. 2024 · Theoretically, this paper uses the algorithm advantages of the BP neural network algorithm to achieve the purpose of early warning of typhoon disaster risk. It constructs a historical building typhoon warning model based on BP neural network to evaluate the risk level of historical buildings. WebIn machine learning, backpropagation is a widely used algorithm for training feedforward artificial neural networks or other parameterized networks with differentiable nodes. [1] [2] It is an efficient application of the Leibniz chain rule (1673) [3] to such networks. [4]
