TFA-Net: A Deep Learning-Based Time-Frequency Analysis Tool

IEEE Transactions on Neural Networks and Learning Systems, 2023
Recently, synchrosqueenzing transform (SST)-based time-frequency analysis (TFA) methods have been developed for achieving the highly concentrated TF representation (TFR). However, SST-based methods suffer from two drawbacks. The first one is that the TFRs are unsatisfactory when dealing with the multicomponent signals, the instantaneous frequencies ...

Time-Frequency Analysis (TFA) Method for Load Identification on Non-Intrusive Load Monitoring

2019 4th International Conference on Information Technology, Information Systems and Electrical Engineering (ICITISEE), 2019
Public awareness of energy conservation can be realized through the process of electricity monitoring so that information can be found related to electricity usage and potential savings that can be made by the community. With the information on the results of this monitoring, the community can manage electricity usage more optimally so that it will ...

The Time-Frequency Analysis (TFA) toolbox: a versatile processing tool for the recognition of magnetospheric and ionospheric signals in Swarm time series

2023
The ongoing Swarm mission of the European Space Agency (ESA) provides an opportunity for a better knowledge of the near-Earth electromagnetic environment, including investigations of ultra-low frequency (ULF) wave events. The Time-Frequency Analysis (TFA) tool is a processing tool established for deriving Pc1 (0.2–5 Hz) and Pc3 (20&#8211 ...
