Understanding the Answer
Let's break down why this is correct
Answer
In nearest‑neighbor un‑embedding, you find the prediction vector that is closest to the input by measuring how far it is from the decision boundaries that separate different classes. The algorithm calculates the distance from the prediction to each of these boundaries, usually using Euclidean distance or another metric, and picks the vector whose distance is smallest. This step lets the model decide which class the prediction most likely belongs to, because the closest boundary tells you which side of the decision line the point falls on. For example, if a prediction lies 0. 3 units from the boundary between class A and B, but 0.
Detailed Explanation
Signed distances give both how far a point is from a boundary and which side of the boundary it lies on. Other options are incorrect because Euclidean distance only measures straight‑line closeness; Manhattan distance counts steps along grid lines.
