The invention discloses a space-time prediction method fusing adaptive selection convolution receptive fields. The core of the space-time prediction method is to introduce an ARFSLSTM module. The ARFSLSTM module fuses an adaptive selection receptive field ARFS module and a convolutional long and short term memory model ConvLSTM, extracts context spatio-temporal information through combined action, and performs accurate modeling on correlation of historical states. And the ARFS module is composed of three parts, namely, Split, Fuse and Select. Through a non-linear method, the ARFS module can aggregate information from a plurality of cores, so that each neuron can adaptively adjust the size of a receptive field based on a plurality of input information scales, thereby realizing fine capture of spatio-temporal data. By connecting a recurrent neural network (RNN), a complete spatio-temporal data modeling network is constructed. The network can deeply capture time-space relations and features in a training stage. In conclusion, by introducing the ARFSLSTM module, accurate capture and prediction of the spatio-temporal data are realized, the uniqueness, innovativeness and superiority of the spatio-temporal data are shown, and a new way is opened up for development of the spatio-temporal prediction field.
