但是有些参数就不适合线性的sampling at radom, 比如 learning rateα,这时可以用 log Andrew 很幽默的讲到了两种选参数的实际场景 pandas vs caviar. pandas approach 一般用在你的算力不够时候,要持续几天的training. Batch norm 我们知道对input layer 做 normalizing, 其实对每一层的输入都可以做normalizing, 这...
注意这里只是我个人对课程的总结,侧重于我薄弱的环节,建议感兴趣的读者还是去Coursera上购买教材,这样学习得才更全面。经费紧张的读者也不用担心,前7天是免费的。 Deep Neural Networks 什么是神经网络? 神经网络 (Neural Network) 并不是一个新鲜的名词,但是随着数据、计算力、理论三方面的突破,近些年来才迎来了寒冬...
在python中不要使用lambda作为变量名,这是一个关键字。 对于neural network,l2也被称为"weight decay",因为在导数项里相当于加入了一项λmw,在更新参数的时候,多减去了weight的某个百分比。 l2 regularization如何prevent overfitting 如果λ很大,那么W就很小,Z=WA+b就会很小,对于tanh函数,当input很小,就近似于一...
