Sample weight support for regression problems about featurewiz HOT 3 CLOSED

Hello kmedved:
It should be possible to send the sample_weight parameter. Let me look into it and update this library if possible.

Hi @kmedved 👍
Sorry it took so long to add sample weight functionality to featurewiz . It now adds sample weights automatically for classification problems. You can see the code here:

if modeltype == 'Multi_Classification':
    wt_array = get_sample_weight_array(y_train)
    dtrain = xgb.DMatrix(x_train, label=y_train, weight=wt_array)

It adds sample weights for multi-class problems and adds scale_pos_weight for binary class problems as you can see here:

scale_pos_weight = get_scale_pos_weight(y_train)

I hope this is good for you. if you want to send in a sample weight separately I need to change the input arguments, hence I thought I will do it automatically. Take a look at the latest version:

pip install featurewiz --upgrade

Thanks
