extrapolator

Data pattern forecaster

An extrapolator is someone or something that extrapolates—that extends known data or trends into unknown territory to make predictions or estimates.

In technical contexts, an extrapolator may be a mathematical function or algorithm that projects values beyond measured points: The climate model uses an extrapolator to forecast temperatures through 2100.
