No ensemble averaging below the black hole threshold

open access: yesJournal of High Energy Physics, 2022
In the AdS/CFT correspondence, amplitudes associated to connected bulk manifolds with disconnected boundaries have presented a longstanding mystery. A possible interpretation is that they reflect the effects of averaging over an ensemble of boundary ...

Analogue Ensemble Averaging Method for Bias Correction of 2-m Temperature of the Medium-Range Forecasts in China

open access: yesAtmosphere, 2022
The 2-m temperature is one of the important meteorological elements, and improving the accuracy of medium- and long-term forecasts of the 2-m temperature is important.

Machine learning-driven modeling of soil plasticity and strength parameters with interpretability insights [PDF]

open access: yesE3S Web of Conferences
This study proposes advanced stacking ensemble machine learning approaches to predict soil Liquidity Index (LI) and Undrained Shear Strength (Su). Over 1,550 LI and 950 Su measurements from global research were employed.

Evaluating State-of-the-Art, Forecasting Ensembles and Meta-Learning Strategies for Model Fusion

open access: yesForecasting, 2022
The techniques of hybridisation and ensemble learning are popular model fusion techniques for improving the predictive power of forecasting methods. With limited research that instigates combining these two promising approaches, this paper focuses on the

Large ensemble modeling of the last deglacial retreat of the West Antarctic Ice Sheet: comparison of simple and advanced statistical techniques [PDF]

open access: yesGeoscientific Model Development, 2016
A 3-D hybrid ice-sheet model is applied to the last deglacial retreat of the West Antarctic Ice Sheet over the last  ∼  20 000 yr. A large ensemble of 625 model runs is used to calibrate the model to modern and geologic data, including reconstructed ...

Ensemble average theory of gravity [PDF]

open access: yesPhysical Review D, 2016
We put forward the idea that all the theoretically consistent models of gravity have contributions to the observed gravity interaction. In this formulation, each model comes with its own Euclidean path-integral weight where general relativity (GR) has automatically the maximum weight in high-curvature regions.

Opening Pandora's box: reducing global circulation model uncertainty in Australian simulations of the carbon cycle [PDF]

open access: yesEarth System Dynamics, 2023
Climate projections from global circulation models (GCMs), part of the Coupled Model Intercomparison Project 6 (CMIP6), are often employed to study the impact of future climate on ecosystems.
