I'd suggest some background in machine learning and neural networks before you start reading the book.<br />
<br />
1) Linear algebra is a must have!<br />
2) Look into the history of neural networks. Start with perceptron and feed forward network with 1 hidden layer before you move onto other architectures - they are fancy, but learning the limitations of perceptron, feed forward networks will truly inspire you to read more.<br />

I'd suggest some background in machine learning and neural networks before you start reading the book.<br />

3) Learn how to interpret weights of neural networks. Hidden layer weights may seem insignificant, but they tell you exactly what/how the network learns.<br />
<br />
IMHO these 3 are necessary to understand why other architectures are required and the type of problems that each architecture can solve. I admit that deep learning is a beast, but it can be tamed by using a systematic approach. Ideally, go through a course on deep learning (there are many in YouTube) and use the book as primary reference material. Greetings Frederick,

<p>You may want to take a course in Linear Algebra before getting into ML. It won't make a lot of sense unless you have a basic understanding of matrices. </p>
