Non-intrusive load monitoring using Short-Time Fourier Transform (STFT)-based Local Phase Quantization (LPQ) features and hybrid deep–classical learning models

PeerJ Computer Science
Background The increasing global energy demand necessitates reliable techniques for appliance-level consumption analysis. Non-Intrusive Load Monitoring (NILM) enables device-level disaggregation from aggregated smart-meter measurements, supporting energy efficiency, demand management, and user awareness. However,

Improved estimation of evolutionary spectrum based on short time Fourier transforms and modified magnitude group delay by signal decomposition

, 2009
A new estimator for evolutionary spectrum (ES) based on short time Fourier transform (STFT) and modified group delay function (MGDF) by signal decomposition (SD) is proposed. The STFT due to its built-in averaging, suppresses the cross terms and the MGDF
