, a model
's quality of tending to converge
on similar predictions
for varying samples of the same population. Distinct from the statistical definition of accuracy
, which is the model's quality of producing predictions close to the theoretical true result.
To illustrate the distinction, if you throw ten darts at the center of a dartboard, and they are scattered loosely around the center, your throws had high accuracy but low precision. If the darts are tightly grouped at a spot on the wall not very close to the dartboard, your throws had high precision but low accuracy.
