In the last chapter we learned that deep neural networks are often much harder to train than shallow neural networks. That's unfortunate, since we have good reason to believe that if we could train deep nets they'd be much more powerful than shallow…

前言: CNN作为DL中最成功的模型之一,有必要对其更进一步研究它.虽然在前面的博文Stacked CNN简单介绍中有大概介绍过CNN的使用,不过那是有个前提的:CNN中的参数必须已提前学习好.而本文的主要目的是介绍CNN参数在使用bp算法时该怎么训练,毕竟CNN中有卷积层和下采样层,虽然和MLP的bp算法本质上相同,但形式上还是有些区别的,很显然在完成CNN反向传播前了解bp算法是必须的.本文的实验部分是参考斯坦福UFLDL新教程UFLDL:Exercise: Convolutional Ne…

做中学(Learning by Doing)之背单词-扇贝网推荐 看完杨贵福老师(博客,知乎专栏,豆瓣)的「继续背单词,8个月过去了」,我就有写这篇文章的冲动了,杨老师说: 有时候我会感觉非常后悔,如果当年更努力一些,早一些拥有现在的词汇量,应该可以看到多少错过的风景.人生苦短,早些开始,早些受益. 我现在所花费的200多天,是我的一些同学当年就已经花费过的--而且不会短很多.在2月初看到7月末的时候,我被这么多个月震惊了,那就是从寒假看到暑假了啊.如果我被那时的漫长天数吓住没有开始,此刻,也还…

<Learning Spark>这本书算是Spark入门的必读书了,中文版是<Spark快速大数据分析>,不过豆瓣书评很有意思的是,英文原版评分7.4,评论都说入门而已深入不足,中文译版评分8.4,评论一片好评,有点意思.我倒觉得这本书可以作为官方文档的一个补充,刷完后基本上对Spark的一些基本概念.码简单的程序是没有问题的了.这本书有一个好处是它是用三门语言写的,Python/Java/Scala,所以适用性很广,我的观点是,先精通一门语言,再去学其他语言.由于我工作中比较常用…

本来这篇是准备5.15更的,但是上周一直在忙签证和工作的事,没时间就推迟了,现在终于有时间来写写Learning Spark最后一部分内容了. 第10-11 章主要讲的是Spark Streaming 和MLlib方面的内容.我们知道Spark在离线处理数据上的性能很好,那么它在实时数据上的表现怎么样呢?在实际生产中,我们经常需要即使处理收到的数据,比如实时机器学习模型的应用,自动异常的检测,实时追踪页面访问统计的应用等.Spark Streaming可以很好的解决上述类似的问题. 了解Spar…

目前,深度学习(Deep Learning,简称DL)在算法领域可谓是大红大紫,现在不只是互联网.人工智能,生活中的各大领域都能反映出深度学习引领的巨大变革.要学习深度学习,那么首先要熟悉神经网络(Neural Networks,简称NN)的一些基本概念.当然,这里所说的神经网络不是生物学的神经网络,我们将其称之为人工神经网络(Artificial Neural Networks,简称ANN)貌似更为合理.神经网络最早是人工智能领域的一种算法或者说是模型,目前神经网络已经发展成为一类多学科交叉的…
