Name nearestneighbors is not defined

WitrynaThe specificity of the k-Nearest Neighbors algorithm is that this formula is computed not at the moment of fitting but rather at the moment of prediction. This isn’t the case for most other models. When a new data point arrives, the kNN algorithm, as the name indicates, will start by finding the nearest neighbors of this new data point.
