- So with both unsupervised and supervised learning, in fact, with any sort of neural network, scale matters.
- Now to do this, people often used something called unsupervised learning, where you don't actually teach the machine anything beforehand.
- And, and you know, this is all unsupervised and directly from the patient's data.

Synonyms

Morphology
unsupervised = supervised (transparent) = un + supervise + ed
The technical ML sense is formed by standard negation of 'supervised' (i.e., 'without supervision/labels'), so the morphological relation is transparent.
Etymology
The word unsupervised is made of un- 'not' and super- 'over' with the idea of 'see', so it keeps the idea of 'not watched'. In machine learning, a helpful way to remember this sense is to think of a computer left alone to find groups or patterns without human labels, so it learns by itself.
