What does the k in k-Nearest Neighbors (k-NN) represent?

Accepted Answer

In k-Nearest Neighbors (k-NN), the k represents the number of nearest training examples considered when making a prediction for a new data point. This means that the algorithm looks at the k closest data points to determine the classification or regression for the new point.
