The invention discloses a prediction method based on periodic feature extraction and time sequence attention, and the method comprises the steps: dividing an original data set into time sequence block data and periodic block data, analyzing the correlation between historical data and current energy consumption through employing a mutual information method and a Pearson method, and providing a basis for the determination of the input features of a time sequence block prediction model. Secondly, time sequence block data is modeled through a TPAnet time sequence attention model, in order to explicitly model periodicity and time sequence of energy consumption data in a neural network, the optimal period of the energy consumption data is analyzed according to STL decomposition and a period amplitude grid optimization algorithm, and a period block is constructed; modeling the periodic block data through an EDAnet coding and decoding attention model; and finally, a linear regression model is adopted ...
