Web1. Algorithm Description BP The neural network is a multi -layer network with an input layer, one or more hidden layers, and an output layer. Each neuron on the implicit layer and the output layer corresponds to a stimulating function and a threshold. The neurons on each layer are connected to the neurons on the adjacent layer through weight. Web翻訳. NEWFF has been obsolete for 4 years. The current function to use for regression/curve-fitting is FITNET. You only have 11 points resulting in 11 equations. By closing your eyes and imagining the plot of T vs P, you will "see" a 3rd order polynomial-type curve with an internal local maximum and an endpoint maximum.
