Fuzzy-Based Time Series Forecasting and Modelling: A Bibliometric Analysis
(2022-07-07)The purpose of this paper is to present the results of a systematic literature review regarding the development of fuzzy-based models for time series forecasting in the period 2017–2021. The study was conducted using a ... -
Gene selection and disease prediction from gene expression data using a two-stage hetero-associative memory
(2019-04-01)In general, gene expression microarrays consist of a vast number of genes and very few samples, which represents a critical challenge for disease prediction and diagnosis. This paper develops a two-stage algorithm that ... -
Generalization of the Hotelling’s t2 decomposition method to the r-chart
(2018-02-14)In this paper, the decomposition of the Mahalanobis distance (MD) and the proportional contribution that each one of the p monitored variables has on the estimated Mahalanobis depth function (MDF) of the R-chart are ... -
Generalized Cauchy–Riemann equations in non-identity bases with application to the algebrizability of vector fields
(2023-03-29)We complete the work done by James A. Ward in the mid-twentieth century on a system of partial differential equations that defines an algebra A for which this system is the generalized Cauchy–Riemann equations for the ... -
Genetic Algorithm for Scheduling Optimization Considering Heterogeneous Containers: A Real-World Case Study
(2020-03-04)In this paper, we develop and apply a genetic algorithm to solve surgery scheduling cases in a Mexican Public Hospital. Here, one of the most challenging issues is to process containers with heterogeneous capacity. Many ... -
Geodesics of Hayward black hole surrounded by quintessence
(2021-02-26)Basing on the ideas used by Kiselev, we study the Hayward black hole surrounded by quintessence. The values critical of mass and the normalization factor are obtained. We also described the horizons and the extremal ... -
