Single and Multi-Sequence Deep Learning Models for Short and Medium Term Electric Load Forecasting

Energies, 2019
Time series analysis using long short term memory (LSTM) deep learning is a very attractive strategy to achieve accurate electric load forecasting. Although it outperforms most machine learning approaches, the LSTM forecasting model still reveals a lack ...

(Multiscale) Cross-Entropy Methods: A Review

Entropy, 2019
Cross-entropy was introduced in 1996 to quantify the degree of asynchronism between two time series. In 2009, a multiscale cross-entropy measure was proposed to analyze the dynamical characteristics of the coupling behavior between two sequences on ...
