    • Blind Radio Tomography 

      Romero, Daniel; Lee, Donghoon; Giannakis, Georgios B. (Journal article; Peer reviewed, 2018)

    • Fast Graph Filters for Decentralized Subspace Projection 

      Romero, Daniel; Ghari, Siavash Mollaebrahim; Beferull-Lozano, Baltasar; Marco, Cesar Asensio (Peer reviewed; Journal article, 2020)
      A number of inference problems with sensor networks involve projecting a measured signal onto a given subspace. In existing decentralized approaches, sensors communicate with their local neighbors to obtain a sequence of ...

    • Inference of Spatio-Temporal Functions Over Graphs via Multikernel Kriged Kalman Filtering 

      Ioannidis, Vassilis N.; Romero, Daniel; Giannakis, Georgios B. (Journal article; Peer reviewed, 2018)

    • Location-Free Spectrum Cartography 

      Teganya, Yves; Romero, Daniel; Lopez-Ramos, Luis M.; Beferull-Lozano, Baltasar (Journal article; Peer reviewed, 2019)

    • Online Topology Identification From Vector Autoregressive Time Series 

      Zaman, Bakht; Lopez Ramos, Luis Miguel; Romero, Daniel; Beferull-Lozano, Baltasar (Peer reviewed; Journal article, 2020)
      Causality graphs are routinely estimated in social sciences, natural sciences, and engineering due to their capacity to efficiently represent the spatiotemporal structure of multi-variate data sets in a format amenable for ...

    • Sparse Online Learning with Kernels using Random Features for Estimating Nonlinear Dynamic Graphs 

      Money, Rohan Thekkemarickal; Krishnan, Joshin P.; Beferull-Lozano, Baltasar (Peer reviewed; Journal article, 2023)
      Online topology estimation of graph-connected time series is challenging in practice, particularly because the dependencies between the time series in many real-world scenarios are nonlinear. To address this challenge, we ...

    • Testing Equality of Multiple Power Spectral Density Matrices 

      Ramirez, David; Romero, Daniel; Via, Javier; Lopez-Valcarce, Roberto; Santamaría, Ignacio (Journal article; Peer reviewed, 2018)
      This paper studies the existence of optimal invariant detectors for determining whether P multivariate processes have the same power spectral density. This problem finds application in multiple fields, including physical ...

    • 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 ...
