Abstract

The invention provides an improved top speed learning model and a method for classifying modes of the top speed learning model, discloses an efficient neural network rapid learning method and a limited top speed learning machine and belongs to the field of mode identification and machine learning. The improved top speed learning model comprises (1) a concept of a limited parameter space, (2) a hypersphere limited condition in the limited parameter concept and (3) output weight learning. According to the concept of the limited parameter space, a lateral inhibition mechanism based on sample prior information is adopted and the content is particularly shown on the aspect of generation of a connection weight from an input layer to a hidden layer; according to the hypersphere limited condition in the limited parameter concept, selection of the connection weight from the input layer to the hidden layer is limited to a hypersphere; according to output weight learning, after a weight of the hidden layer is selected from the limited parameter space, learning is trained through a top speed learning machine model based on least squares, and finally an output weight of the model is obtained. According to the method, the classification and identification effects of the model can be greatly improved, and the training speed can be greatly increased.
