Electrical load forecasting in disaggregated levels using Fuzzy ARTMAP artificial neural network and noise removal by singular spectrum analysis
(2020-07-01)
Electrical load forecasting in disaggregated levels is a difficult task due to time series randomness, which leads to noise and consequently affects the quality of predictions. To mitigate this problem, noise removal using ...
Electricity consumption forecasting using singular spectrum analysis
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-03-01)
Singular Spectrum Analysis (SSA) is a non-parametric technique that allows the decomposition of a time series into signal and noise. Thus, it is a useful technique to trend extraction, smooth and filter a time series. The ...
Spectral analysis for perturbed operators on Carnot groups
(Birkhauser Verlag AG, 2017)
© 2017, Springer International Publishing. Let G be a Carnot group of homogeneous dimension M and Δ its horizontal sublaplacian. For α∈ (0 , M) we show that operators of the form Hα: = (- Δ) α+ V have no singular spectrum, ...
A new approach for structural damage detection exploring the singular spectrum analysis
(2017-05-01)
This article presents a novel approach for damage detection applied to structural health monitoring systems exploring the residues obtained from singular spectrum analysis. In this technique, a lead zirconate titanate patch ...
