Biomedical Image Classification in a Big Data Architecture Using Machine Learning Algorithms.

TL;DR: A survey of classification algorithms for biomedical images can be found in this paper, where the authors describe how these algorithms can be applied to a big data architecture by using the Spark framework and propose the classification workflow based on the observed optimal algorithms, Support Vector Machine and Deep Learning as drawn from the literature.
Journal ArticleDOI

Control of multistability with selection of chaotic attractor: application to image encryption

TL;DR: A linear augmentation control scheme is used to control a periodic attractor in the windows of multistability to a final chaotic attractor which survives to the variation of initial seed useful for image encryption.
Journal ArticleDOI

Control of Coexisting Attractors with Preselection of the Survived Attractor in Multistable Chua’s System: A Case Study

TL;DR: Nonlinear dynamical tools including bifurcation diagrams, standard Lyapunov exponents, phase portraits, and cross section of initial conditions are exploited to reveal the selection scenarios of the survived attractor in the multistability control process of Chua's system.
Journal ArticleDOI

An Overview of Supervised Machine Learning Methods and Data Analysis for COVID-19 Detection.

TL;DR: In this article, support vector machine (SVM) was used as the best performant for the COVID-19 diagnosis, achieving an accuracy of 99.29%, sensitivity of 92.79%, and specificity of 100% with the dataset from Kaggle (https://www.kaggle.org/record/3886927#.YIluB5AzbMV).
