Practical tasks focus a lot on implementing the "under the hood" mechanics of certain deep learning steps, which I personally did not enjoy as modern frameworks do that for you. Helpful YN Y. N. 7 years ago A nice course on convolutional...
Course Notes:Neural Networks and Deep Learning Week 1 Introduction to Deep Learning What is neural network? 这里通过房价预测的例子,说明single neural network和multiple neural network。 图1 单一输入的房价预测图 如图1所示,Single neural network只有一个输入为房屋的大小,输出为房屋的价格,可以使用简单的ReLU...
just seen that our artificial neuron has a lot of difficulty learning when it's badly wrong - far more difficulty than when it's just a little wrong. What's more, it turns out that this behaviour occurs not just in this toy model, but in more general networks. Why is learning so ...

ReLU函数:a = max(0,z),性能较好,作为default function使用。 Leaky ReLU函数:z < 0时,a = max(0.01z, z);z > 0时,a = max(0,z)。 Why do you need non-linear activation functions? 假设我们使用的激活函数为线性激活函数,以恒等激活函数为例,进行说明。恒等激活函数,将输入的值进行线性计算之后...
