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...
What are Neural Networks in Machine Learning? Neural networks in machine learningrefer to a set of algorithms designed to help machines recognize patterns without being explicitly programmed. They consist of a group of interconnected nodes. These nodes represent the neurons of the biological brain. Th...

神经网络算法最早是人们希望模仿大脑的学习功能而想出来的。 一个神经元,有多个树突(Dendrite)作为信息的输入通道,也有多个轴突(Axon)作为信息的输出通道。一个神经元的输出可以作为另一个神经元的输入。神经元的概念和多分类问题的分类器概念很相近,都是可以接收多个输入,在不同的权值(weights)下产生出多个不同的输...

Neural networks are made up of a collection of processing units called "nodes." These nodes pass data to each other, just like how in a brain, neurons pass electrical impulses to each other. Neural networks are used in machine learning, which refers to a category of computer programs that ...

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: ...
Machine learning and neural networks are two important technologies in the field of artificial intelligence (AI). While they are often used together, they are not the same thing. Here, we will explore the differences between machine learning and neural networks and how they are related. ...
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...
