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: "Unzip the archive and locate weka.jar within the extracted archive."

A block of code is set as follows:

data.defineSingleOutputOthersInput(outputColumn); 

EncogModel model = new EncogModel(data); 
model.selectMethod(data, MLMethodFactory.TYPE_FEEDFORWARD);
model.setReport(new ConsoleStatusReportable()); 
data.normalize(); 

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

$ java -cp moa.jar -javaagent:sizeofag.jar moa.gui.GUI

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text as bold. Here is an example: "We can convert it to a Comma Separated Value (CSV) format by clicking File | Save As and picking CSV in the saving dialog."
