Combiner taking too much time to execute

[FahadShahid143]

Combiner takes too much time to execute. Below code takes several hours to execute. Is there a way to improve it?

combiner = toad.transform.Combiner()
combiner.fit(X=x_train,
y=x_train['label'],
method='chi',
min_samples = 0.05,
exclude=exclude_list)

@FahadShahid143 yes, it does only merge two values in a single step when using 'chi', it will take a long time when the unique value is too much, so I think if it can merge multiple values in a single step will improve the speed.
I will work on it, and release the new version as soon as possible
