Fractional-order calculus is about the differentiation and integration of non-integer orders. Fractional calculus (FC) is based on fractional-order thinking (FOT) and has been shown to help us to understand complex systems better, improve the processing of complex signals, enhance the control of complex systems, increase the performance of optimization, and even extend the enabling of the potential for creativity. In this article, the authors discuss the fractional dynamics, FOT and rich fractional stochastic models. First, the use of fractional dynamics in big data analytics for quantifying big data variability stemming from the generation of complex systems is justified. Second, we show why fractional dynamics is needed in machine learning and optimal randomness when asking: “is there a more optimal way to optimize?”. Third, an optimal randomness case study for a stochastic configuration network (SCN) machine-learning method with heavy-tailed distributions is discussed. Finally, views on big data and (physics-informed) machine learning with fractional dynamics for future research are presented with concluding remarks. https://www.mdpi.com/1099-4300/23/3/297/pdf

小数分频电路的优越性能和潜在应用吸引了学者和研究人员的广泛关注。 最近,常规电路理论的基础已经扩展到包括新的广义元素和分数阶元素。 众所周知,电路理论是电磁场理论的一个特例,经典电路元件的特性可以用优雅的电磁学解释来描述。 本文考虑分数阶时间导数,提出了分数阶元素的电磁场解释:分数阶准静态展开,表示分数阶电感器,分数阶电容器和分数阶互感器。麦克斯韦方程。 它表明分数阶元素也可以解释为分数电磁系统。 当元素阶数等于1时,分数阶元素的解释与经典电路元素的解释分别匹配:L,C和互感器。
