Abstract

Prediction of Lotka-Volterra equations has always been a complex problem due to their dynamic properties. In this paper, we present an algorithm for predicting the Lotka-Volterra equation and investigate the prediction for both the original system and the system driven by noise. This demonstrates that deep learning can be applied in dynamics of population. This is the first study that uses deep learning algorithms to predict Lotka-Volterra equations. Several numerical examples are presented to illustrate the performances of the proposed algorithm, including Predator nonlinear breeding and prey competition systems, one prey and two predator competition systems, and their respective systems. All the results suggest that the proposed algorithm is feasible and effective for predicting Lotka-Volterra equations. Furthermore, the influence of the optimizer on the algorithm is discussed in detail. These results indicate that the performance of the machine learning technique can be improved by constructing the neural networks appropriately.

利用混合深度网络预测Lotka‐Volterra方程的解
由于Lotka-Volterra方程的动力学性质,其预测一直是一个复杂的问题。本文提出了一种预测Lotka-Volterra方程的算法,并对原始系统和受噪声驱动的系统进行了预测。这表明深度学习可以应用于人口动态。这是第一个使用深度学习算法来预测Lotka-Volterra方程的研究。本文给出了几个数值例子来说明该算法的性能,包括捕食者非线性繁殖和猎物竞争系统、一个猎物和两个捕食者竞争系统以及它们各自的系统。结果表明,该算法对Lotka-Volterra方程的预测是可行和有效的。此外,还详细讨论了优化器对算法的影响。这些结果表明,通过适当构造神经网络可以提高机器学习技术的性能。
