Full Annotation#

Labelling every example fully, the most costly supervision setting.

✨ AI-generated content. This page was written with the assistance of an AI language model and is provided as a learning aid. Despite careful review, it may still contain mistakes, omissions, or out-of-date information. Whether you are new to the topic, a team lead, or a senior practitioner, treat it as a starting point rather than an authoritative reference: read it critically and independently verify anything you act on (code, commands, figures, and factual claims) against official documentation and primary sources before relying on it.

What it is#

Full annotation means labeling every example in a dataset with its ground-truth target — the complete, high-quality supervision that classic supervised learning assumes. Each image gets its boxes, each sentence its tags.

The cost#

It is manual, slow, and expensive — often the most tedious part of an ML project — and requires annotators following guidelines, whose disagreements become a data-quality issue (measured with inter-annotator agreement). At scale, labeling everything is simply infeasible.

Why it persists#

Despite the cost, fully annotated data gives the strongest signal and remains the go-to for production and the gold-standard benchmark. Its expense is exactly what motivates weak, semi-, and self-supervised learning, which trade some label quality for far less human effort.
