[HTML][HTML] Multicomponent signals interference detection exploiting HP-splines frequency parameter

V Bruni, R Campagna, D Vitulano - Applied Numerical Mathematics, 2025 - Elsevier
Multicomponent signals play a key role in many application fields, such as biology, audio
processing, seismology, air traffic control and security. They are well represented in the time …

Data-driven extrapolation via feature augmentation based on variably scaled thin plate splines

R Campagna, E Perracchione - Journal of Scientific Computing, 2021 - Springer
The data driven extrapolation requires the definition of a functional model depending on the
available data and has the application scope of providing reliable predictions on the …

Feature augmentation for numerical inversion of multi-exponential decay curves

R Campagna, E Perracchione - AIP Conference Proceedings, 2022 - pubs.aip.org
Multi-exponential decay curves describe the nuclear magnetic resonance response to
radiofrequency exposure. This problem is strongly related to finding a non-negative function …

Stable interpolation with exponential-polynomial splines and node selection via greedy algorithms
