felsiq / dbcv Goto Github PK

Hey and thanks for this package... since the other one available doesn't seem to follow the reference implementation and is inactive it is nice to see something being maintained.

I'm getting the duplicate error when running my code (even though the data has previously being de-duplicated using pandas)
"Duplicated samples have been found in X."

I saw that the init function allows me to disable duplicate checks, however since its not documented I'm wondering what the implications of this are.

When running with duplication checks off, I am getting a result, however I am also getting the warning: "overflow encountered in power core_dists = np.power(dists, -d).sum(axis=-1, keepdims=True) / (n - 1 + 1e-12)"
Is this related or something to worry about?

Thanks again and all the best!

Hello!

I am encountering the following error while executing. Will be grateful if you may please check:-

Hi,
thanks for the python implementation of DBCV.
I used your implementation on the dataset_1.txt provided by the authors of DBCV paper from this link: https://github.com/pajaskowiak/dbcv .

With your implementation I get a score of 0.85434 while the authors report a score of 0.6149 with their matlab implementation.
Any idea on what is causing this difference in the results?

Thank you!
