<p>In this monkey example, we (human) could infer the <strong>model</strong> (set of rules). Software Engineering is when a human makes a rule that the machine follows.</p>
<p>Most Machine learning classifiers, the “rules” of the <strong>model</strong> are unknown to us. We only get hte output of the machine assigned classes. Machine learning is when the machine creates the rules for the machine to follow.</p>
