The selection for node number of the hidden layer is realized by adopting the gradient descent method in the RBF neural network training algorithm and combining with L1 and L2 regularization,so as to estimate the remaining capacity for the lead-acid battery of the base station. The fuzzy control idea is used to improve generalization capability. The simulated annealing algorithm is introduced to reduce times of repetition training. The results of the Matlab simulation show that the improved RBF neural netwo...
