‎A spectral collocation method‎ for solving stochastic fractional integro-differential equation [PDF]

Mathematics and Computational Sciences
In this paper‎, ‎a numerical scheme based on shifted Vieta-Lucas polynomials is utilised to solve mentioned equation‎. ‎The main characteristic of the presented method is to approximate Brownian motion with help of the Gauss-Legendre quadrature‎, ‎which ...

The stochastic collocation Monte Carlo sampler: highly efficient sampling from ‘expensive’ distributions

Quantitative finance (Print), 2018
In this article, we propose an efficient approach for inverting computationally expensive cumulative distribution functions. A collocation method, called the Stochastic Collocation Monte Carlo sampler (SCMC sampler), within a polynomial chaos expansion ...

L‐VISP: LSTM Visualization for Interpretable Symptom Prediction in Patient Cohorts

Computer Graphics Forum, EarlyView.
L‐VISP is a human‐machine solution that uses visual analytics for LSTM modelling in clinical research. L‐VISP uses custom visual encodings to make multiple LSTM variants interpretable, supporting a full range of analysis, from understanding model operations and evaluating performance to interpreting results in a clinical context.

Application of Legendre spectral-collocation method to delay differential and stochastic delay differential equation

AIP Advances, 2018
Explicit solutions to delay differential equation (DDE) and stochastic delay differential equation (SDDE) can rarely be obtained, therefore numerical methods are adopted to solve these DDE and SDDE.

Visual Ensemble Analysis With Deep Learning Prediction for Studying the Effect of Tissue Properties on Radiofrequency Ablation

Computer Graphics Forum, EarlyView.
We present an interactive visual analysis tool to study how patient‐specific tissue properties influence radiofrequency ablation outcomes. Using a deep‐learning surrogate model, we predict ablation volumes for unseen parameter settings with accuracy superior to interpolation, supporting improved treatment planning. Abstract Radiofrequency (RF) ablation

The Influence of Random Element Displacement on DOA Estimates Obtained with (Khatri–Rao-)Root-MUSIC

Sensors, 2014
Although a wide range of direction of arrival (DOA) estimation algorithms has been described for a diverse range of array configurations, no specific stochastic analysis framework has been established to assess the probability density function of the ...

Multi‐Objective Optimization of a Hydro‐Economic Model in an Over‐Allocated Agricultural Basin

Groundwater, EarlyView.
Abstract Groundwater depletion for agricultural irrigation poses significant environmental and economic challenges. This study introduces a proof‐of‐concept that combines hydro‐economic modeling, scenario‐based modeling, and multi‐objective optimization to manage pumping curtailment in an over‐allocated basin in the western United States.

The Role of Remittances and FDI for the Current Account: The Case of Cambodia

Journal of Money, Credit and Banking, EarlyView.
Abstract This paper develops a small open economy real‐business‐cycle model to examine the dynamics of Cambodian current account. Differing from previous studies, our model incorporates both net foreign direct investment (FDI) and remittances as additional sources of macro‐economic fluctuations. Our results reveal that these two factors, especially FDI,

Is acquisition‐related foreign direct investment during an economic crisis detrimental for domestic innovation?

The Scandinavian Journal of Economics, EarlyView.
Abstract We study how acquisition‐related foreign direct investment during economic crises affects R&D investments and the direction of innovation of target firms, compared with acquisitions made during periods of strong economic growth. Using a panel of Spanish firms, we find that foreign multinationals cherry‐pick the best domestic firms ...
