How can I use ndcg_score?
I need to use sklearn.metrics.ndcg_score(y_true, y_score, k=5), but I dont know what is y_true, y_score and k. I read the documentation and I dont understand how to use.
The documentation:
Parameters:
y_true : array, shape = [n_samples]
Ground truth (true labels represended as integers).
y_score : array, shape = [n_samples, n_classes]
Predicted probabilities.
k : int
Rank.
Returns:
score : float
Can you help me?
