[C1W4] Neural Networks and Deep Learning - Deep Neural Networks

第四周:深层神经网络(Deep Neural Networks) 深层神经网络(Deep L-layer neural network) 目前为止我们学习了只有一个单独隐藏层的神经网络的正向传播和反向传播,还有逻辑回归,并且你还学到了向量化,这在随机初始化权重时是很重要.本周所要做的是把这些理念集合起来,就可以执行你自己的深度神经网络. 严格上来说逻辑回归也是一个一层的神经网络,浅与深仅仅是指一种程度.有一个隐藏层的神经网络,就是一个两层神经网络.当我们算神经网络的层数时,我们不算输入层,我们只…

Deep learning与Neural Network

深度学习是机器学习研究中的一个新的领域,其动机在于建立.模拟人脑进行分析学习的神经网络,它模仿人脑的机制来解释数据,例如图像,声音和文本.深度学习是无监督学习的一种. 深度学习的概念源于人工神经网络的研究.含多隐层的多层感知器就是一种深度学习结构.深度学习通过组合低层特征形成更加抽象的高层表示属性类别或特征,以发现数据的分布式特征表示. Deep learning本身算是machine learning的一个分支,简单可以理解为neural network的发展.大约二三十年前,neural n…

deep learning 的综述

从13年11月初开始接触DL,奈何boss忙or 各种问题,对DL理解没有CSDN大神比如 zouxy09等深刻,主要是自己觉得没啥进展,感觉荒废时日(丢脸啊,这么久....)开始开文,即为记录自己是怎么一步一个逗比的走过的路的,也为了自己思维更有条理.请看客,轻拍,(如果有错,我会立马改正,谢谢大家的指正.==!其实有人看没人看都是个问题.哈哈) 推荐 tornadomeet 的博客园学习资料 http://www.cnblogs.com/tornadomeet/category/4976…
