costsensitive's Issues

Add `costsensitive` to Conda Forge

Could costsensitive be added to conda-forge?

problems with installing

Hello,

I have problems with the installation.
I installed Cython and Visual Buildstudio, however there are further issues:

any idea?

Cost-sensitive binary classification

Can cost-sensitive classifier (say WeightedAllPairs) be used for binary classification problem. We noticed assertion error for all the methods except CostProportionateClassifier. Could you please explain why other methods are not suitable for binary classification.
And can you suggest which method would be appropriate for cost-sensitive binary classifier.

Following the example and in the fit function I got the error

Hi ,

I am following the example provided in the ipython notebook and when it calls the fit:
Traceback (most recent call last):
File "multiclass.py", line 71, in
costsensitive_WAP.fit(X_train, C_train)
File "/home/fang587/.local/lib/python2.7/site-packages/costsensitive/init.py", line 83, in fit
self.classifiers[ix].fit(X_take, y_take, sample_weight=w_take)
File "/home/fang587/.local/lib/python2.7/site-packages/sklearn/linear_model/logistic.py", line 1288, in fit

estimator=estimator)
File "/home/fang587/.local/lib/python2.7/site-packages/sklearn/utils/validation.py", line 582, in check_array
context))
ValueError: Found array with 0 sample(s) (shape=(0, 54)) while a minimum of 1 is required.

The shape of my X_train and C_train looks like this:
(522910, 54)
(522910, 7)

I have tested with different classifiers, with different inputs, I always get this error.

How do we get other evaluation metrics to run

Hi David !
I was wondering, how can we check for the evaluation metrics like precision, recall, f1-score, and AUROC using the cost sensitive library? Based on the documentation, it didn't talk about how to address these. We can only get the accuracy. I'd appreciate your feedback on this. Look forward to hearing from you.

Installation problem

Hey, hope you're doing well.

I'm trying to install your package with a 3.10 python, but I ran into an error. The first one was this one :

Do you have any idea of what I can do to correct this one ?
The error means that the initialization in the instruction 'for' OpenMP has an incorrect form.
Thanks !

'Z' in line #495 in init.py should be 'sample_weight'

In my understanding, the 'Z' in line #495 in init.py should be 'sample_weight'.
