Dynamic network identification from non-stationary vector autoregressive time series
Lopez-Ramos, Luis M.; Romero, Daniel; Zaman, Bakht; Beferull-Lozano, Baltasar (Chapter; Peer reviewed, 2018) -
Localization-Free Power Cartography
Teganya, Yves; Lopez-Ramos, Luis M.; Romero, Daniel; Beferull-Lozano, Baltasar (Chapter; Peer reviewed, 2018)Spectrum cartography constructs maps of metrics such as channel gain or received signal power across a geographic area of interest using measurements of spatially distributed sensors. Applications of these maps include ... -
Location-Free Spectrum Cartography
Teganya, Yves; Romero, Daniel; Lopez-Ramos, Luis M.; Beferull-Lozano, Baltasar (Journal article; Peer reviewed, 2019) -
Online Hyperparameter Search Interleaved with Proximal Parameter Updates
Lopez-Ramos, Luis M.; Beferull-Lozano, Baltasar (Chapter, 2020)There is a clear need for efficient hyperparameter optimization (HO) algorithms for statistical learning, since commonly applied search methods (such as grid search with N-fold cross-validation) are inefficient and/or ... -
Online Machine Learning for Graph Topology Identification from Multiple Time Series
Zaman, Bakht (Doctoral Dissertations at the University of Agder; no. 298, Doctoral thesis, 2020)High dimensional time series data are observed in many complex systems. In networked data, some of the time series are influenced by other time series. Identifying these relations encoded in a graph structure or topology ... -
A Trainable Approach to Zero-delay Smoothing Spline Interpolation
Moreno, Emilio Ruiz; Lopez-Ramos, Luis M.; Beferull-Lozano, Baltasar (Peer reviewed; Journal article, 2023)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 zerodelay response; that is, the smooth signal must ...
