Recently, several deep learning approaches have been proposed in which several nonlinear functions are applied to the input to obtain the output. In this paper, we introduce a novel method to improve the performance of deep learning models in time series forecasting. This method divides the model into hierarchies or levels from simpler to more complex ones. Simpler levels handle smoothed versions of the input, whereas the most complex level processes the original time series. This method follows the human learning process where general\/simpler tasks are performed first, and afterward, more precise\/harder ones are accomplished. Our proposed methodology has been applied to the LSTM architecture, showing remarkable performance in various time series. In addition, a comparison is reported including a standard LSTM and novel methods such as DeepAR, Temporal Fusion Transformer, NBEATS and Echo State Network.<\/jats:p>","DOI":"10.1093\/jigpal\/jzae030","type":"journal-article","created":{"date-parts":[[2024,5,16]],"date-time":"2024-05-16T09:05:49Z","timestamp":1715850349000},"page":"986-1003","source":"Crossref","is-referenced-by-count":4,"title":["From
