3 - General Architecture of the learning algorithm It’s time to design a simple algorithm to distinguish cat images from non-cat images. You will build a Logistic Regression, using a Neural Network mindset. The following Figure explains why Logistic Regre…
Part 1:Python Basics with Numpy (optional assignment) 1 - Building basic functions with numpy Numpy is the main package for scientific computing in Python. It is maintained by a large community (www.numpy.org). In this exercise you will learn several key numpy…
一、对于神经网络中深度学习的介绍 在学习系统中哪些可修改元素应该对其成功或者失败负责?是什么改变了它们来提高了表现?这一切被称为“基本信用分配问题”。通用问题解决者有一般的信用分配方法,这些方法在各种理论意义上是时间最优的。然而,当前的调查主要关注人工神经网络中较窄,但是在商业上非常重要的深度学习的子领域上。我们对神经网络中通过可能的许多计算计算阶段的精确信用分配感兴趣。 浅层学习模型已经存在了大约几十年。具有几个连续非线性神经元层的模型可以追溯到至少20世纪60年代、70年代。在此时,有人提出了一种在离散、可微分…
