To get the most out of this book

We recommend you have experience with Python 3 so that you know what the syntax looks like. You will need to run either Linux or Windows on a machine with a decent amount of memory and CPU power, as the samples in this book can take a long time to run on an older machine. If you are lucky enough to have a gaming graphics card in your machine from NVIDIA, we definitely recommend looking at the instructions on how to install the GPU version of CNTK, as this can speed up the samples by quite a large factor. Some sections in the book assume that you know a little bit about Java or C#. Although not required, it is useful to have a basic understanding of the syntax of one or more of these languages.
