Credit card fraud detection through logistic regression, k-means, and deep learning.
Home Page: https://www.kaggle.com/dalpozz/creditcardfraud
Hello, thanks a lot for your work.
I think the way you compute accuracy for the kmeans algorithm is incorrect. kmeans outputs cluster numbers but does not know which cluster corresponds to fraud or real. Hence, we shouldnt be able to compare y_test = 1 with prediction = 1.
What do you think?
Best regards
If you do this, the oversampling algorithm will leak information from the test set onto the training sets, which explains why you got such a magical f1 score.
