Detecting the periodicity of highly irregularly sampled light-curves with Gaussian processes: the case of SDSSJ025214.67-002813.7
Stefano Covino, Felipe Tobar, Aldo Treves
Based on a 20-year-long multiband observation of its light-curve, it was conjectured that the quasar SDSSJ025214.67-002813.7 has a periodicity of ~4.4 years. These observations wer…
Nonstationary multi-output Gaussian processes via harmonizable spectral mixtures
Matías Altamirano, Felipe Tobar
Kernel design for Multi-output Gaussian Processes (MOGP) has received increased attention recently. In particular, the Multi-Output Spectral Mixture kernel (MOSM) arXiv:1709.01298…
Bayesian autoregressive spectral estimation
Alejandro Cuevas, Sebastián López, Danilo Mandic +1
Autoregressive (AR) time series models are widely used in parametric spectral estimation (SE), where the power spectral density (PSD) of the time series is approximated by that of…
Detection of blue whale vocalisations using a temporal-domain convolutional neural network
Bryan Sagredo, Sonia Español-Jiménez, Felipe Tobar
We present a framework for detecting blue whale vocalisations from acoustic submarine recordings. The proposed methodology comprises three stages: i) a preprocessing step where the…
Late reverberation suppression using U-nets
Diego León, Felipe Tobar
In real-world settings, speech signals are almost always affected by reverberation produced by the working environment; these corrupted signals need to be \emph{dereverberated} pri…
Data Science for Engineers: A Teaching Ecosystem
Felipe Tobar, Felipe Bravo-Marquez, Jocelyn Dunstan +4
We describe an ecosystem for teaching data science (DS) to engineers which blends theory, methods, and applications, developed at the Faculty of Physical and Mathematical Sciences,…
