  • 适用于需要物理合理性与专家先验的动态系统建模任务。

本文提出并分析了一种新型吸引子模糊认知图(Attractor FCM)。该模型不依赖赫布或代理机制,而是基于梯度下降、物理约束及雅可比结构。其核心特征包括:残差记忆机制保留系统历史状态;通过时间反向传播更新权重;固定点锚点递归调节,确保系统收敛至稳定点。误差最小化通过反向传播实现,保证梯度准确性。新提出的算法结合牛顿法寻找系统固定点,并利用自适应项动态调整权重,根据激活函数饱和度实时调整优化路径,防止过早陷入局部极小。此外,更新过程受因果掩码过滤,融入物理规律与专家先验,使模型能高效减少至目标误差。

原文摘要 · Abstract (English)

In this paper an attractor FCM is created, tested, and analyzed. This FCM is neither a hebbian based nor agentic, nor a hybrid; it rather is a gradient descent based, physics constrained, Jacobian version of an FCM. Moreover, this model has several quirks; it uses residual memory, back propagation through time, and a fixed point anchor that is recursively implemented to update its weights. The residuals update the recursive part without losing the system memory. The model's anchor enables it to converge in a fixed point for which back propagation through time unrolls it and ensures that the error minimization is for an accurate gradient. Furthermore, a new learning algorithm is utilized. The Newton's method finds the system's fixed point attractor and then gradient descend is adaptively changing the landscape; an adaptive term is used to directly manipulate the weights through the attractor dynamics. As the adaptive term changes, the descent through the landscape is constantly adjusting according to sigmoid saturation, and that prevents premature convergence to a local minimum. Lastly, the updates are filtered by causal mask that informs the network about the physics, respecting the initial expert based opinions, for which model reduces the error to the target in an efficient way.
