WebThe issue of multi-step-ahead time series prediction is a daunting challenge of predictive modeling. In this work, we propose a multi-output iterative prediction model with stacking LSTM neural network (MO-LSTMs). In the proposed model, we utilize a stacking LSTM network that consists of multiple hidden layers to learn the features of time series data, … WebI've been trying to figure out how to stack when the data has a time series nature.

WebJan 20, 2024 · Regular time series: are those that have a record in each uniform period of time. A daily series of temperatures can be considered a regular series since we expect exactly one record per day, one record per unit of time. Irregular time series: are those collected without a defined frequency. An example is the log of accesses to a website. WebJul 14, 2024 · The framework involves three stages:(1) data preprocessing using the wavelet transform, which is applied to decompose the stock price time series to eliminate noise; (2) application of the stacked autoencoders, which has a deep architecture trained in an unsupervised manner; and (3) the use of long-short term memory with delays to generate …
