Knn give more weight to specific feature in distance

Question

I\'m using the Kobe Bryant Dataset. I wish to predict the shot_made_flag with KnnRegressor.

I\'ve used game_date to extract year and

Answer 1

Just add on Shihab's answer regarding distance computation. Can use scipy pdist as suggested in this post, which is faster and more efficient.

from scipy.spatial.distance import pdist, minkowski, squareform

# create the custom weight array
weight = ...
# calculate pairwise distances, using Minkowski norm with custom weights
distances = pdist(X, minkowski, 2, weight)
# reformat the result as a square matrix
distances_as_2d_matrix = squareform(distances)
