Dimension
How many numbers a vector has. A vector with 3 numbers is 3-dimensional.
The count of numbers in a vector is its dimension.
[3, 1]has dimension 2. The customer vector has dimension 3. The word vectors that power AI search often have 1,536 numbers. You can't draw 1,536 directions, but every rule you'll learn works the same way. You practice on flat 2-number vectors you can see, then trust the same rules in bigger spaces.
