Supervised learning

A category of machine learning that uses labeled data when training algorithms to predict outcomes.

The Explain card

Plain English: Supervised learning trains an algorithm on labeled data, where each example already carries the right answer, so the model learns to predict those answers for new inputs.
Example: A malware classifier is trained on millions of files, each tagged "malicious" or "benign" by analysts. Later it scores an unknown executable based on what it learned from the tagged ones.
Why it matters: The labels are the ground truth the model trusts. Mislabeled or deliberately flipped labels teach the model to wave through exactly the threats you wanted caught.
Hook: Learning with an answer key, so guard the answer key.

In a sentence

On the malware pipeline, supervised learning scores each unknown PE file after analysts have tagged a training set malicious or benign.

Why these words

supervised Latin supervisus, overseen, from supervidere, to look over marks the named activity as happening under an overseer rather than alone
learning Old English leornung, the act of getting knowledge supplies the head noun, the getting of knowledge the phrase ascribes to a machine

Where it came from

Origin: English compound from Latin supervisus (overseen, from super, over, and videre, to see) and Old English leornung (the act of getting knowledge)
Entered the language: 1960s
What changed: Supervise had meant to oversee a person at work since the 1600s. Learning had meant a person acquiring knowledge. Pattern-recognition labs in the 1960s borrowed the schoolroom sense of a teacher watching the work, and the pair became the ordinary name for training that shows each input already paired with its target.

How it is spelled

Pattern: super- keeps its Latin spelling and its sense of over
Pattern: -vise from Latin videre always takes s, never z
Pattern: -ed marks the past participle used as an adjective
Pattern: -ing turns a verb into a noun of activity
Breaks the pattern: the noun phrase stays two words; the hyphen appears only when it modifies another noun
Breaks the pattern: supervise is not an -ize verb; the s is from vis, see, so American spelling still writes s
