BERS: Locally Optimal Continuous Algorithm for Maritime Weather Routing with Just-in-Time Arrival

Daniel Precioso, Francisco Suárez, Javier Jiménez de la Jara +2

Maritime weather routing must optimize route geometry under dynamic wind-wave conditions, obstacle constraints, and fixed-arrival requirements. We present Bézier Evolve and Refine…

Global Sensitivity Analysis of Uncertain Parameters in Bayesian Networks

Rafael Ballester-Ripoll, Manuele Leonelli

Traditionally, the sensitivity analysis of a Bayesian network studies the impact of individually modifying the entries of its conditional probability tables in a one-at-a-time (OAT…

The YODO algorithm: An efficient computational framework for sensitivity analysis in Bayesian networks

Rafael Ballester-Ripoll, Manuele Leonelli

Sensitivity analysis measures the influence of a Bayesian network's parameters on a quantity of interest defined by the network, such as the probability of a variable taking a spec…

Are Quantum Computers Practical Yet? A Case for Feature Selection in Recommender Systems using Tensor Networks

Artyom Nikitin, Andrei Chertkov, Rafael Ballester-Ripoll +2

Collaborative filtering models generally perform better than content-based filtering models and do not require careful feature engineering. However, in the cold-start scenario coll…

Global sensitivity analysis in probabilistic graphical models

Rafael Ballester-Ripoll, Manuele Leonelli

We show how to apply Sobol's method of global sensitivity analysis to measure the influence exerted by a set of nodes' evidence on a quantity of interest expressed by a Bayesian ne…

Cherry-Picking Gradients: Learning Low-Rank Embeddings of Visual Data via Differentiable Cross-Approximation

Mikhail Usvyatsov, Anastasia Makarova, Rafael Ballester-Ripoll +3

We propose an end-to-end trainable framework that processes large-scale visual data tensors by looking at a fraction of their entries only. Our method combines a neural network enc…
