Question & Answer
Choose the Best Answer
The class vectors are not properly defined in the embedding space
The decision boundary is too complex for the nearest-neighbor approach
The distances used for classification are calculated incorrectly
The dimensionality of the vectors is too high for effective classification
Understanding the Answer
Let's break down why this is correct
Nearest‑neighbor assumes that points close together belong to the same class. Other options are incorrect because The mistake is thinking the vectors themselves are wrong; Wrong distances would create systematic errors, not a single misclassification.
