Nonnegative OPLS for Supervised Design of Filter Banks: Application to Image and Audio Feature Extraction
Sergio Muñoz-Romero, Jerónimo Arenas García, Vanessa Gómez-Verdejo
Audio or visual data analysis tasks usually have to deal with high-dimensional and nonnegative signals. However, most data analysis methods suffer from overfitting and numerical pr…
Regularized Multivariate Analysis Framework for Interpretable High-Dimensional Variable Selection
Sergio Muñoz-Romero, Vanessa Gómez-Verdejo, Jerónimo Arenas-García
Multivariate Analysis (MVA) comprises a family of well-known methods for feature extraction which exploit correlations among input variables representing the data. One important pr…
Combinations of Adaptive Filters
Jerónimo Arenas-García, Luis A. Azpicueta-Ruiz, Magno T. M. Silva +2
Adaptive filters are at the core of many signal processing applications, ranging from acoustic noise supression to echo cancelation, array beamforming, channel equalization, to mor…
Unveiling the semantic structure of text documents using paragraph-aware Topic Models
Simón Roca-Sotelo, Jerónimo Arenas-García
Classic Topic Models are built under the Bag Of Words assumption, in which word position is ignored for simplicity. Besides, symmetric priors are typically used in most application…
Censoring Diffusion for Harvesting WSNs
Jesus Fernandez-Bes, Rocío Arroyo-Valles, Jerónimo Arenas-García +1
In this paper, we analyze energy-harvesting adaptive diffusion networks for a distributed estimation problem. In order to wisely manage the available energy resources, we propose a…
Adaptive Diffusion Schemes for Heterogeneous Networks
Jesus Fernandez-Bes, Jerónimo Arenas-García, Magno T. M. Silva +1
In this paper, we deal with distributed estimation problems in diffusion networks with heterogeneous nodes, i.e., nodes that either implement different adaptive rules or differ in…
