Zusammenfassung: | The invention relates to an artificial intelligence technology, and discloses a time sequence prediction method, device and equipment and a storage medium, and the method comprises the steps: obtaining a time sequence data set; decomposing the time sequence data set through discrete wavelet transform to obtain a plurality of sub-sequence data; performing feature extraction on the plurality of sub-sequence data to obtain a plurality of feature vectors; inputting each feature vector into a corresponding prediction model for prediction to obtain a prediction result; weighted summation is carried out on the prediction results, a final result is obtained, and the weight of each prediction result is obtained through training of a meta-learning model. According to the invention, the prediction accuracy is improved.
