Subject Ability to offer initial coefficients in ml.LogisticRegression
Date Tue, 20 Oct 2015 07:34:48 GMT
Hi all,

I noticed that in ml.classification.LogisticRegression, users are not
allowed to set initial coefficients, while it is supported in
mllib.classification.LogisticRegressionWithSGD.

Sometimes we know specific coefficients are close to the final optima.
e.g., we usually pick yesterday's output model as init coefficients
since the data distribution between two days' training sample
shouldn't change much.

Is there any concern for not supporting this feature?
