Recurrent neural networks (RNNs) as one of the representative deep learning methods, has restricted its generalization ability because of its indigestion hidden-layer information presentation. In order to properly handle of hidden-layer information, directly reduce the risk of over-fitting caused by too many neuron nodes, as well as realize the goal of streamlining the number of hidden layer neurons, and then improve the generalization ability of RNNs, the hidden-layer information of RNNs is precisely analyzed by using the unsupervised clustering methods, such as Kmeans, Kmeans++ and Iterative self-organizing data analysis (Isodata), to divide the similarity of raw data points, and maps the hidden-layer information into the feature space where data separation is easily implemented. Experiments based on dataset from the National Renewable Energy Laboratory (NREL) is proposed to demonstrate the performance of the proposed approaches, the average forecasting errors of which is respectively increased by 2.1%, 7.6%, 10.26% with respect to 6-steps, 12-steps and 18-steps in four seasons over the ones that achieved using the traditional deep learning approaches.
