用随机神经元构建新模型,精准逼近随机过程。

Kantorovich-Type Stochastic Neural Network Operators for the Mean-Square Approximation of Certain Second-Order Stochastic Processes

  • 引入随机神经元驱动的新型神经网络算子,直接建模随机性。
  • 理论证明均方收敛,误差随连续性模量减小而降低。
  • 适合需要精确模拟随机信号的科研与工程场景。

人工神经网络算子(ANNOs)广泛用于近似确定性输入输出函数,但其在随机动力系统中的扩展仍不充分。本文提出一类新型【Kantorovich型随机神经网络算子(K-SNNOs)】,将随机性通过【随机神经元】和【随机积分器】引入,而非仅作用于系数。该框架可继承底层过程的概率结构,适用于随机信号的建模与逼近。我们建立了K-SNNOs对目标随机过程的均方收敛性,并给出了以连续性模量表示的定量误差估计。数值模拟验证了理论结果:样本路径重建准确,均方误差(MSE)迅速衰减。图形结果包括逐样本逼近与经验MSE变化趋势,表明所提算子具有鲁棒性与高效性。

原文摘要 · Abstract (English)

Artificial neural network operators (ANNOs) have been widely used for approximating deterministic input-output functions; however, their extension to random dynamics remains comparatively unexplored. In this paper, we construct a new class of \textbf{Kantorovich-type Stochastic Neural Network Operators (K-SNNOs)} in which randomness is incorporated not at the coefficient level, but through \textbf{stochastic neurons} driven by stochastic integrators. This framework enables the operator to inherit the probabilistic structure of the underlying process, making it suitable for modeling and approximating stochastic signals. We establish mean-square convergence of K-SNNOs to the target stochastic process and derive quantitative error estimates expressing the rate of approximation in terms of the modulus of continuity. Numerical simulations further validate the theoretical results by demonstrating accurate reconstruction of sample paths and rapid decay of the mean square error (MSE). Graphical results, including sample-wise approximations and empirical MSE behaviour, illustrate the robustness and effectiveness of the proposed stochastic-neuron-based operator.
