What is an AI Domain?

An AI is only as clever as what it was trained on. Feed it numbers and it learns about numbers. Feed it photographs and it learns about photographs. That is the whole idea behind domains.

1Domains, in one sentence

AI Domain

With respect to the type of data fed into it, an AI model belongs to one of three domains: Statistical Data, Computer Vision and Natural Language Processing.

Three domains, three kinds of data

Pick a domain and it rises. What is standing on the pedestal is the data that domain is fed. Drag sideways to turn.

Same machine, three different inputs. The input is what decides the domain.

2The three domains

Domain	Fed with	It learns to
Statistical Data	Numbers and tables	Find meaning in large amounts of data
Computer Vision (CV)	Images and video	See — get information out of pixels
Natural Language Processing (NLP)	Words, written and spoken	Read and listen to human language

Three students, three subjects

Give one student only maths problems, one only photographs, one only poems. All three are equally clever, and each becomes good at a different thing. The subject they were given decides what they can do. An AI model is the same, and the subject is the data.

3The question that decides it

Ask: what is going IN?

Not what the project is about — what is going into the machine.
Numbers and tables → Statistical Data.
Pictures or video → Computer Vision.
Words, typed or spoken → NLP.

A hospital project could be any of the three. Predicting patient numbers from records is Statistical Data. Reading an X-ray is Computer Vision. Understanding what a patient typed into a form is NLP. “A hospital project” tells you nothing; the input tells you everything.
