人工神经网络(Artificial Neural Networks,ANNs)是一种受到生物神经系统启发的计算模型,已经在多个领域取得了巨大的成功。其中,反向传播神经网络(Backpropagation Neural Network,BP神经网络)是最常见和广泛应用的神经网络之一。BP神经网络被广泛用于模式识别、函数逼近、预测分析等任务,具有强大的自适应学习和非线性建模能力...
2.3、BP(反向传递)神经网络概述:概述、1、Backpropagation is a common method of teaching artificial neural networks how to perform a given task. 2、It is a supervised learning method, and is a generalization of the delta rule. It requires a teacher that knows, or can calculate, the desired ou...
3. Backpropagation requires that the activation function used by the artificial neurons (or “nodes”) be differentiable. 学习算法 –Phase 1: Propagation 1. Forward propagation of a training pattern’s input through the neural network in order to generate the propagation’s output activations. ...
反向传播算法(Backpropagation)是训练人工神经网络(Artificial Neural Network,ANN)的最常用且最有效方法。其基本流程包括前向传播和反向传播两个阶段。前向传播时,输入数据从网络的输入层开始,经过隐藏层,最终到达输出层并给出预测结果;反向传播时,根据预测结果与实际结果的差异,从输出层开始,依次...
