Question & Answer
Choose the Best Answer
Nearest-neighbor un-embedding can be used to improve classification accuracy by utilizing distance metrics.
The signed distances calculated in nearest-neighbor un-embedding represent the probability of class membership.
Nearest-neighbor un-embedding relies solely on Euclidean distance to determine the closest class vector.
It is essential to normalize the class vectors before applying nearest-neighbor un-embedding for accurate results.
Nearest-neighbor un-embedding is only applicable in binary classification scenarios.
Understanding the Answer
Let's break down why this is correct
The method uses distances to decide which class a point belongs to, so it can make predictions more accurate. Other options are incorrect because Signed distances tell how far a point is from a boundary, not how likely it is to belong to a class; While Euclidean distance is common, the method can use other metrics like Manhattan or cosine.
