Unsupervised learning(非监督学习) 发现输入的良好内在表达形式。 提供输入的紧凑、低维度表达。 由已经学到的特征来提供输入的经济性高维度表达。 聚类是极度稀疏的编码形式。仅仅有一维非零特征。 神经网络的不同类型 Feed-forward neural networks (前向传播神经网络) 超过一层隐含层即为深度神经网络。 Recurrent n...
Lecture 08 RNN 一、序列建模 记忆列表模型只是在序列上用来分类的一种模型,我们能够通过其他方法来生成序列。 一种非常自然的生成序列的方法是建立一个有着自己内部动态的多隐状态模型。隐状态的进化是依据它内部动态而定的,而且同时也可以生成观测值(就是预测值),从而可以得到很多不同的模型: 1、信息可以在他的...
Neural Networks for Machine Learning by Geoffrey Hinton (4),一种能够学习家谱关系的简单神经网络血缘一共同拥有12种关系:son,daughter,nephew,niece,father,mother,uncle,aunt,brother,sister,husband,wife有1个英国家庭以及1个意大利家庭,每一个家庭有12个人。
本文为Neural Networks for Machine Learning的第二次课程(回复关键字"NNML2"下载第二讲的视频与PDF课件) 神经网络使用的是学习算法,此算法受到我们对大脑汲取知识过程的理解所启发而产生,但是对其评估需按照实际应用中的效果,如语音识别、物体识别、图像检索以及推荐用户可能喜欢的产品的能力。随着计算机功能变得越来越强...

As usual, we use gradient descent (called Backpropagation in neural networks) to minimize cost function. But we need to calculate the partial derivatives of the cost function, which for neural network can be complicated and need special techniques. The technique we use here is: ...
