Re: [scikit-learn] Clarification regarding SGDClassifier

I think your use of "X" in X_mod should be "X_train" instead, as X_mod is currently using unshuffled indices while X_check uses the shuffled indices. Virus-free. www.avast.co

[scikit-learn] Decision stubs?

Is it possible to efficiently get at the branch statistics that decision tree algorithms iterate over in scikit? For example if the root population has the class counts in the output vector: c0: 5000 c1: 500 Then I'd like to iterate over: # For a boolean (2 valued category) f1=True:

[scikit-learn] Getting weight coefficient of logistic regression from a pipeline

Hello, I am wondering if it's possible to get the weight coefficients of logistic regression from a pipeline? For instance, I have the followings: > clf_lr = LogisticRegression(penalty='l1', C=0.1) > pipe_lr = Pipeline([['sc', StandardScaler()], ['clf', clf_lr]]) > pipe_lr.fit(X, y) Does pipe_

No, we do not have a way to get the coefficients with respect to the input (pre-scaling) space. On 28 August 2017 at 13:20, Raga Markely wrote: > Hello, > > I am wondering if it's possible to get the weight coefficients of logistic > regression from a pipeline? > > For instance, I have the follo
