Online Gradient Computation for Warping Gaussian Process Transformations
Emilio Ruiz-Moreno, Konstantinos Slavakis, Baltasar Beferull-Lozano
Warped Gaussian processes (GPs) handle non-Gaussian observations by mapping them into a latent standard GP via a parametric transformation called warping. Existing streaming varian…
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…
An Online Multiple Kernel Parallelizable Learning Scheme
Emilio Ruiz-Moreno, Baltasar Beferull-Lozano
The performance of reproducing kernel Hilbert space-based methods is known to be sensitive to the choice of the reproducing kernel. Choosing an adequate reproducing kernel can be c…
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…
