Conventions used

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

Code in text: 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: “The only dependency on using POJO models is the h2o-genmodel.jar file.”

A block of code is set as follows:

import h2o
h2o.init()

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

data_frame = h2o.import_file("Dataset/iris.data")

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

mkdir H2O_POJO
cd H2O_POJO 

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “You can simply click the Download POJO button to download the model as a POJO.”
