Know the Vocabulary

This lesson uses the terms below many times. Read them once now, and come back here when a later section needs one.

• Decision: A point in a design where you must pick one of two or more options, such as batch or online inference.
• Deciding variable: The one fact about the problem that picks the answer. For example: does the prediction need information that exists only at request time?
• Default: The option you start with when nothing in the question argues against it. You say it out loud, and you say what would change it.
