Lévy Interest Rate Models with a Long Memory

open access: yesRisks, 2021
This article proposes an interest rate model ruled by mean reverting Lévy processes with a sub-exponential memory of their sample path. This feature is achieved by considering an Ornstein–Uhlenbeck process in which the exponential decaying kernel is ...

Kernel estimators of asymptotic variance for adaptive Markov chain Monte Carlo

open access: yes, 2011
We study the asymptotic behavior of kernel estimators of asymptotic variances (or long-run variances) for a class of adaptive Markov chains. The convergence is studied both in $L^p$ and almost surely.

Obtaining Land Cover Type for Urban Storm Flood Model in UAV Images Using MRF and MKFCM Clustering Techniques

open access: yesISPRS International Journal of Geo-Information, 2019
With the accelerated urbanization process, cities are suffering from extremely heavy rain and urban storm water logging disasters in recent years. To provide reliable and effective information for urban management and emergency decision-making, the ...

An adaptive Markov chain algorithm applied over map-matching of vehicle trip GPS data

open access: yesGeo-spatial Information Science, 2021
Markov chains have frequently been applied to match the probable routes with a set of GPS trip data that a pilot vehicle is emitting over a specific graph road network.

Spatiotemporal heterogeneity and driving factors of PM2.5 reduction efficiency: An empirical analysis of three urban agglomerations in the Yangtze River Economic Belt, China

open access: yesEcological Indicators, 2021
Understanding the spatiotemporal heterogeneities of PM2.5 reduction efficiency (PRE) and their driving factors are substantially critical for the atmospheric environmental governance.

Triangular norm-based measures and their Markov kernel representation

open access: yes, 1991
We approach the problem whether left-continuous triangular norm-based valuations (called T -measures or T -probability measures) defined on triangular normbased tribes of the unit cube can be disintegrated by Markov kernels. We prove that each T -measure

Bayesian nonparametric analysis of reversible Markov chains [PDF]

open access: yes, 2013
We introduce a three-parameter random walk with reinforcement, called the $(\theta,\alpha,\beta)$ scheme, which generalizes the linearly edge reinforced random walk to uncountable spaces.

Hybrid Markov weighted fuzzy kernel time series with red Piranha Walrus optimization for gold price forecasting

open access: yesAin Shams Engineering Journal
The price of gold is crucial to the world’s financial and economic systems; hence precise estimation of gold prices is essential. The current study proposes a hybrid Markov Weighted Fuzzy Kernel Time Series framework for gold price prediction, together ...

Representative Points Based on Power Exponential Kernel Discrepancy

open access: yesAxioms, 2022
Representative points (rep-points) are a set of points that are optimally chosen for representing a big original data set or a target distribution in terms of a statistical criterion, such as mean square error and discrepancy.
