Brain kernel: A new spatial covariance function for fMRI data [PDF]
NeuroImage, 2021 A key problem in functional magnetic resonance imaging (fMRI) is to estimate spatial activity patterns from noisy high-dimensional signals. Spatial smoothing provides one approach to regularizing such estimates. However, standard smoothing methods ignore

Introduction to Neutrosophic Stochastic Processes [PDF]
Neutrosophic Sets and Systems, 2023 In this article, the definition of literal neutrosophic stochastic processes is presented for the first time in the form 𝒩𝑡 = 𝜉𝑡 + 𝜂𝑡𝐼 ;𝐼 2 = 𝐼 where both {𝜉(𝑡),𝑡 ∈ 𝑇} and {𝜂(𝑡),𝑡 ∈ 𝑇} are classical real valued stochastic processes.

FUNCTIONAL SEQUENTIAL TREATMENT ALLOCATION WITH COVARIATES [PDF]
Econometric Theory, 2023 We consider a sequential treatment problem with covariates. Given a realization of the covariate vector, instead of targeting the treatment with highest conditional expectation, the decision-maker targets the treatment which maximizes a general functional of the conditional potential outcome distribution, e.g., a conditional quantile, trimmed mean, or ...

Dizhen xuebao, 2020 基于非均匀分布的陆地重力观测数据，重构局部重力场模型是区域重力资料处理与解释的重要环节。本文对比了多种局部重力场建模方法，并以EGM2008模型提供的自由空气重力异常模型重采样数据进行测试，综合比较了不同噪声条件下不同建模方法的实际效果。结果表明：在不同噪声水平下，优选出适合重力位场问题的协方差函数后，最小二乘配置法的建模效果优于其它方法。

Geography, Environment, Sustainability, 2022 Bandwidth plays a crucial role in the Geographically Weighted Regression modelas it affects the model’s ability to describe spatial dependencies. If the bandwidth is too large, the model will be similar to a normal regression model.
