    Interdisciplinary Comments Highlighting the Importance of SupraMicrobiological Approaches to Covid-19 Pandemic by Rodrigo Riera, Ada M. Herrera, Ricardo A. Rodríguez

    Published 2024-05-01
    “…The results suggest that (a) zoonotic diseases do not coincide with what is expected according to the orthodox Darwinian approach on at least two points (gradualism, and evolutionary process at the population scale); (b) socioeconomic niches and socio-diversity (the social equivalent of biodiversity) connected to them act as strong selective pressures either for or against pandemics; (c) socioeconomic development is equivalent to a drift from r to K in human systems, and as a result there is a drift from K to r in ecosystems, which favors a tendency to increase pandemic frequency; (d) eco-historical analysis indicates that those countries or areas that display a faster rate of economic growth act as socio-economic Maxwell’s demons that modulate, either voluntarily or involuntarily, the emergence of pandemics.…”

    Adversarial example defense algorithm for MNIST based on image reconstruction by Zhongyuan QIN, Zhaoxiang HE, Tao LI, Liquan CHEN

    Published 2022-02-01
    “…With the popularization of deep learning, more and more attention has been paid to its security issues.The adversarial sample is to add a small disturbance to the original image, which can cause the deep learning model to misclassify the image, which seriously affects the performance of deep learning technology.To address this challenge, the attack form and harm of the existing adversarial samples were analyzed.An adversarial examples defense method based on image reconstruction was proposed to effectively detect adversarial examples.The defense method used MNIST as the test data set.The core idea was image reconstruction, including central variance minimization and image quilting optimization.The central variance minimization was only processed for the central area of the image.The image quilting optimization incorporated the overlapping area into the patch block selection.Considered and took half the size of the patch as the overlap area.Using FGSM, BIM, DeepFool and C&W attack methods to generate adversarial samples to test the defense performance of the two methods, and compare with the existing three image reconstruction defense methods (cropping and scaling, bit depth compression and JPEG compression).The experimental results show that the central variance minimization and image quilting optimization algorithms proposed have a satisfied defense effect against the attacks of existing common adversarial samples.Image quilting optimization achieves over 75% classification accuracy for samples generated by the four attack algorithms, and the defense effect of minimizing central variance is around 70%.The three image reconstruction algorithms used for comparison have unstable defense effects on different attack algorithms, and the overall classification accuracy rate is less than 60%.The central variance minimization and image quilting optimization proposed achieve the purpose of effectively defending against adversarial samples.The experiments illustrate the defense effect of the proposed defense algorithm in different adversarial sample attack algorithms.The comparison between the reconstruction algorithm and the algorithm shows that the proposed scheme has good defense performance.…”
