Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "In addition, alpha is the learning rate, vb is the bias of the visible layer, hb is the bias of the hidden layer, and W is the weight matrix. The sampling function sample_prob is the Gibbs-Sampling function and it decides which node to turn on."

A block of code is set as follows:

import mxnet as mx
tensor_cpu = mx.nd.zeros((100,), ctx=mx.cpu())
tensor_gpu = mx.nd.zeros((100,), ctx=mx.gpu(0))

Any command-line input or output is written as follows:

$ sudo add-apt-repository ppa:graphics-drivers/ppa -y
$ sudo apt-get update
$ sudo apt-get install -y nvidia-375 nvidia-settings

Bold: Indicates a new term, an important word, or words that you see onscreen.
