Trend Filtering via Empirical Mode Decompositions [PDF]
, 2011 The present work is concerned with the problem of extracting low-frequency trend from a given time series. To solve this problem, the authors develop a nonparametric technique called empirical mode decomposition (EMD) trend filtering. A key assumption is

EMPIRICAL MODE DECOMPOSITION BASED ON THETA METHOD FOR FORECASTING DAILY STOCK PRICE
Journal of ICT, 2020 Forecasting is a challenging task as time series data exhibit many features that cannot be captured by a single model. Therefore, many researchers have proposed various hybrid models in order to accommodate these features to improve forecasting results.

Intrinsic coupling modes reveal the functional architecture of cortico-tectal networks [PDF]
Science Advances, 2015 Summary In the absence of sensory stimulation or motor output, the brain exhibits complex spatiotemporal patterns of intrinsically generated neural activity. However, little is known about how such patterns of activity are correlated between cortical and subcortical brain areas. Here, we investigate the large-scale correlation structure

Open charm hadroproduction and the charm content of the proton
, 2009 We advocate charmed-hadron inclusive hadroproduction as a laboratory to probe intrinsic charm (IC) inside the colliding hadrons. Working at next-to-leading order in the general-mass variable-flavor-number scheme endowed with non-perturbative ...

Morphological Filtering Enhanced Empirical Wavelet Transform for Mode Decomposition
IEEE Access, 2019 Empirical wavelet transform (EWT) has been successfully utilized for decomposing multi-component signals into intrinsic mode functions. However, it suffers from the spectrum subdividing problem when signals contain non-stationary components which overlap
