Risk, uncertainty, and leverage

Economic Modelling, 2020
Using mostly theoretical models and traditional risk/uncertainty measures (VIX index, panic, precaution, scary bad news, etc.), the current literature tries to clarify the risk/uncertainty-deleveraging pattern. The findings are not sufficient to explain the dynamic empirical relationship between modern risk/uncertainty indicators and leverage.

The Gaussian Process Modeling Module in UQLab [PDF]

Journal of Soft Computing in Civil Engineering, 2018
We introduce the Gaussian process (GP) modeling module developed within the UQLab software framework. The novel design of the GP-module aims at providing seamless integration of GP modeling into any uncertainty quantification workflow, as well as a ...

Neural correlates of perceptual texture change during active touch

Frontiers in Neuroscience, 2023
IntroductionTexture changes occur frequently during real-world haptic explorations, but the neural processes that encode perceptual texture change remain relatively unknown.

A reproducible notebook to acquire, process and analyse satellite imagery

REGION, 2020
Satellite imagery is often used to study and monitor Earth surface changes. The open availability and extensive temporal coverage of Landsat imagery has enabled changes in temperature, wind, vegetation and ice melting speed for a period of up to 46 years.

Risk, Unexpected Uncertainty, and Estimation Uncertainty: Bayesian Learning in Unstable Settings [PDF]

, 2011
Recently, evidence has emerged that humans approach learning using Bayesian updating rather than (model-free) reinforcement algorithms in a six-arm restless bandit problem. Here, we investigate what this implies for human appreciation of uncertainty.

Modelling the Vulnerability of Financial Accounting Systems during Global Challenges: A Comparative Analysis

Mathematics, 2022
In times of crisis, the vulnerability of global financial markets can be considered as an element in the analysis of economic stability and sustainable development, which also indicates significant differences in the recognition of economic capital.

Estimation of failure probability in braced excavation using Bayesian networks with integrated model updating

Underground Space, 2020
A probabilistic model is proposed that uses observation data to estimate failure probabilities during excavations. The model integrates a Bayesian network and distanced-based Bayesian model updating.

Probabilistic characterization of underground stratigraphy and its uncertainty based on cone penetration test

Yantu gongcheng xuebao, 2018
A Bayesian framework is developed to probabilistically identify the underground stratigraphy based on Ic data. The proposed Bayesian framework identifies the most probable soil layer boundaries with the consideration of spatial variability of Ic and ...
