摘要

众所周知,误差函数是决定神经网络收敛性、稳定性和泛化能力的关键因素之一。对于大多数前馈神经网络,通常选择平方误差函数作为训练网络的误差函数。然而,基于平方误差函数的网络会导致收敛速度缓慢,在实际训练过程中容易陷入局部最优。最新研究发现,与平方误差函数相比,基于熵误差函数的梯度法在迭代过程中测量模型输出的概率分布与真实标签的概率分布之间的差异,更能处理分类问题中的不确定性,不易陷入局部最优,学习收敛速度更快。本文提出了一种基于熵误差函数的 Sigma-Pi-Sigma 神经网络批量梯度法,并严格证明了新算法在批量输入模式下的弱收敛性和强收敛性。最后,通过仿真验证了算法的理论结果和有效性。

Convergence analysis of a novel high order networks model based on entropy error function

It is generally known that the error function is one of the key factors that determine the convergence, stability and generalization ability of neural networks. For most feedforward neural networks, the squared error function is usually chosen as the error function to train the network. However, networks based on the squared error function can lead to slow convergence and easily fall into local optimum in the actual training process. Recent studies have found that, compared to the squared error function, the gradient method based on the entropy error function measures the difference between the probability distribution of the model output and the probability distribution of the true labels during the iterative process, which can be more able to handle the uncertainty in the classification problem, less likely to fall into a local optimum and can learn to converge more rapidly. In this paper, we propose a batch gradient method for Sigma-Pi-Sigma neural networks based on the entropy error function and rigorously demonstrate the weak and strong convergence of the new algorithm in the batch input mode. Finally, the theoretical results and effectiveness of the algorithm are verified by simulation.
