VG-TIE: An interpretable tabular-to-image encoding method based on visibility graphs
David Chushig-Muzo, Luis M. López-Ramos, Ángeles Rodríguez de Cara +3
Tabular-to-image encoding methods enable the application of models based on both convolutional neural networks and vision transformers to tabular data, transforming feature vectors…
Consistent Signal Reconstruction from Streaming Multivariate Time Series
Emilio Ruiz-Moreno, Luis Miguel López-Ramos, Baltasar Beferull-Lozano
Digitalizing real-world analog signals typically involves sampling in time and discretizing in amplitude. Subsequent signal reconstructions inevitably incur an error that depends o…
A Trainable Approach to Zero-delay Smoothing Spline Interpolation
Emilio Ruiz-Moreno, Luis Miguel López-Ramos, Baltasar Beferull-Lozano
The task of reconstructing smooth signals from streamed data in the form of signal samples arises in various applications. This work addresses such a task subject to a zero-delay r…
