Integrating Domain Knowledge in Data-driven Earth Observation with Process Convolutions

no code implementations16 Apr 2021 Daniel Heestermans Svendsen, Maria Piles, Jordi Muñoz-Marí, David Luengo, Luca Martino, Gustau Camps-Valls

We specifically propose the use of a class of GP convolution models called latent force models (LFMs) for EO time series modelling, analysis and understanding.

Pattern Recognition Scheme for Large-Scale Cloud Detection over Landmarks

no code implementations8 Dec 2020 Adrián Pérez-Suay, Julia Amorós-López, Luis Gómez-Chova, Jordi Muñoz-Marí, Dieter Just, Gustau Camps-Valls

Landmark recognition and matching is a critical step in many Image Navigation and Registration (INR) models for geostationary satellite services, as well as to maintain the geometric quality assessment (GQA) in the instrument data processing chain of Earth observation satellites.

Emulation as an Accurate Alternative to Interpolation in Sampling Radiative Transfer Codes

no code implementations7 Dec 2020 Jorge Vicent, Jochem Verrelst, Juan Pablo Rivera-Caicedo, Neus Sabater, Jordi Muñoz-Marí, Gustau Camps-Valls, José Moreno

Computationally expensive Radiative Transfer Models (RTMs) are widely used} to realistically reproduce the light interaction with the Earth surface and atmosphere.

Active Learning Methods for Efficient Hybrid Biophysical Variable Retrieval

no code implementations7 Dec 2020 ochem Verrelst, Sara Dethier, Juan Pablo Rivera, Jordi Muñoz-Marí, Gustau Camps-Valls, José Moreno

Kernel-based machine learning regression algorithms (MLRAs) are potentially powerful methods for being implemented into operational biophysical variable retrieval schemes.

Randomized kernels for large scale Earth observation applications

no code implementations7 Dec 2020 Adrián Pérez-Suay, Julia Amorós-López, Luis Gómez-Chova, Valero Laparra, Jordi Muñoz-Marí, Gustau Camps-Valls

Dealing with land cover classification of the new image sources has also turned to be a complex problem requiring large amount of memory and processing time.

Nonlinear Distribution Regression for Remote Sensing Applications

no code implementations7 Dec 2020 Jose E. Adsuara, Adrián Pérez-Suay, Jordi Muñoz-Marí, Anna Mateo-Sanchis, Maria Piles, Gustau Camps-Valls

When the target variable is available at a resolution that matches the remote sensing observations, standard algorithms such as neural networks, random forests or Gaussian processes are readily available to relate the two.

Fusing Optical and SAR time series for LAI gap filling with multioutput Gaussian processes

no code implementations5 Dec 2020 Luca Pipia, Jordi Muñoz-Marí, Eatidal Amin, Santiago Belda, Gustau Camps-Valls, Jochem Verrelst

The availability of satellite optical information is often hampered by the natural presence of clouds, which can be problematic for many applications.

Fair Kernel Learning

no code implementations16 Oct 2017 Adrián Pérez-Suay, Valero Laparra, Gonzalo Mateo-García, Jordi Muñoz-Marí, Luis Gómez-Chova, Gustau Camps-Valls

It has been shown that not including sensitive features that bias fairness, such as gender or race, is not enough to mitigate the discrimination when other related features are included.

A Unified SVM Framework for Signal Estimation

no code implementations21 Nov 2013 José Luis Rojo-Álvarez, Manel Martínez-Ramón, Jordi Muñoz-Marí, Gustavo Camps-Valls

On the one hand, the signal model equation is written in reproducing kernel Hilbert spaces (RKHS) using the well-known RKHS Signal Model formulation, and Mercer's kernels are readily used in SVM non-linear algorithms.
