Understanding the Answer

Let's break down why this is correct

Answer

Nearest‑Neighbor Un‑embedding is a technique that lets a model decide the class of a sample by comparing it to known examples, just as GPS navigation helps you decide where to go by comparing your current location to known roads. In both cases a system looks at known points and picks the closest match to guide a decision. For GPS, the “decision” is which path to follow, so the analogous task is route planning. Thus, GPS navigation is to route planning as Nearest‑Neighbor Un‑embedding is to multi‑class classification.

Detailed Explanation

Nearest-Neighbor Un-embedding looks for the class vector that is closest to a prediction. Other options are incorrect because The idea of finding lost items focuses on searching for something that is missing, not on picking the nearest option; Estimating travel time is about measuring how long a trip will take, not about choosing the closest destination.
