The capabilities of natural neural systems have inspired both new generations of machine learning algorithms as well as neuromorphic, very large-scale integrated circuits capable of fast, low-power information processing. However, it has been argued that

During learning, the brain modifies synapses to improve behaviour. In the cortex, synapses are embedded within multilayered networks, making it difficult to determine the effect of an individual synaptic modification on the behaviour of the system. The backpropagation algorithm solves this problem in ...

2、BackpropagationAlgorithm 同线性回归和逻辑回归用梯度下降来求解损失函数的最小值一样,我们用BP算法(反向传播算法)来求解神经网络中损失函数的最小值。首先,以一个4层的神经网络来计算前向传播过程(即第四周的神经网络左到右顺序计算过程)。 接着引入误差概念(下图中不考虑正则项,即lamba=0) 分类的结果有多个...
