Probabilistic Performance-Pattern Decomposition (PPPD): analysis framework and applications to stochastic mechanical systems

no code implementations4 Mar 2020 Ziqi Wang, Marco Broccardo, Junho Song

Since the early 1900s, numerous research efforts have been devoted to developing quantitative solutions to stochastic mechanical systems.

Neural Network Applications in Earthquake Prediction (1994-2019): Meta-Analytic Insight on their Limitations

no code implementations2 Oct 2019 Arnaud Mignan, Marco Broccardo

In the last few years, deep learning has solved seemingly intractable problems, boosting the hope to find approximate solutions to problems that now are considered unsolvable.

A novel active learning-based Gaussian process metamodelling strategy for estimating the full probability distribution in forward UQ analysis

no code implementations27 Aug 2019 Ziqi Wang, Marco Broccardo

This paper proposes an active learning-based Gaussian process (AL-GP) metamodelling method to estimate the cumulative as well as complementary cumulative distribution function (CDF/CCDF) for forward uncertainty quantification (UQ) problems.

Active Learning Computational Efficiency +1

One neuron is more informative than a deep neural network for aftershock pattern forecasting

2 code implementations3 Apr 2019 Arnaud Mignan, Marco Broccardo

We reformulate the 2017 results in probabilistic terms using logistic regression (i. e., one neural network node) and obtain AUC = 0. 85 using 2 free parameters versus the 13, 451 parameters used by DeVries et al. (2018).
