Parametric Learning of Associative Functional Networks Through a Modified Memetic Self-adaptive Firefly Algorithm
Authors: Gálvez, Akemi,Iglesias, Andrés,Osaba, Eneko,Del Ser, Javier
Functional networks are a powerful extension of neural networks where the scalar weights are replaced by neural functions. This paper concerns the problem of parametric learning of the associative model, a functional network that represents the associativity operator. This problem can be formulated…

Question Answering When Knowledge Bases are Incomplete
Authors: Camille Pradel,Damien Sileo,Álvaro Rodrigo,Anselmo Peñas,Eneko Agirre
While systems for question answering over knowledge bases (KB) continue to progress, real world usage requires systems that are robust to incomplete KBs. Dependence on the closed world assumption is highly problematic, as in many practical cases the information is constantly evolving and KBs cannot…

Spiking Neural Networks and online learning: An overview and perspectives
Authors: Lobo, Jesus L.,Del Ser, Javier,Bifet, Albert,Kasabov, Nikola
Applications that generate huge amounts of data in the form of fast streams are becoming increasingly prevalent, being therefore necessary to learn in an online manner. These conditions usually impose memory and processing time restrictions, and they often turn into evolving environments where a…

Robust combination of the Morris and Sobol methods in complex multidimensional models
Authors: Raúl Prellezo,Inmaculada Arostegui,Inmaculada Arostegui,Dorleta Garcia
Conducting global sensitivity analysis using variance decomposition methods in complex simulation models with many input factors is usually unaffordable. An alternative is to first apply a screening method to reduce the number of input factors and then apply a variance decomposition method to the…

Atmospheric Dynamics and Vertical Structure of Uranus and Neptune’s Weather Layers
Authors: Ricardo Hueso,Agustín Sánchez-Lavega
The Icy Giants Uranus and Neptune have similar rotation periods, large orbital inclinations and intense zonal winds at the visible cloud level. The winds are organized into three broad jets: a zonal jet that flows to the West at low latitudes and single jets that flow to the East in each hemisphere…

Refined isogeometric analysis for fluid mechanics and electromagnetics
Authors: David Pardo,David Pardo,David Pardo,Victor M. Calo,Victor M. Calo,Daniel Garcia
Starting from a highly continuous isogeometric analysis discretization, we introduce hyperplanes that partition the domain into subdomains and reduce the continuity of the discretization spaces at these hyperplanes. As the continuity is reduced, the number of degrees of freedom in the system grows…

Hazes and clouds in a singular triple vortex in Saturn's atmosphere from HST/WFC3 multispectral imaging
Authors: Agustín Sánchez-Lavega,Patrick G. J. Irwin,T. del Río-Gaztelurrutia,J. F. Sanz-Requena,J. F. Sanz-Requena,Santiago Pérez-Hoyos
In this paper we present a study of the vertical haze and cloud structure over a triple vortex in Saturn's atmosphere in the planetographic latitude range 55N-69N (del Rio- Gaztelurrutia et al. , 2018) using HST/WFC3 multispectral imaging. The observations were taken during 29-30 June and 1 July…

Variational formulations for explicit Runge-Kutta Methods
Authors: Victor M. Calo,Victor M. Calo,Elisabete Alberdi,David Pardo,David Pardo,David Pardo,Judit Muñoz-Matute
Variational space-time formulations for Partial Differential Equations have been of great interest in the last decades. While it is known that implicit time marching schemes have variational structure, the Galerkin formulation of explicit methods in time remains elusive. In this work, we prove that…

Saturn’s convective storms usually fall in two categories. One consists of mid-sized storms ∼2,000 km wide, appearing as irregular bright cloud systems that evolve rapidly, on scales of a few days. The other includes the Great White Spots, planetary-scale giant storms ten times larger than the mid-…
