[Scikit-learn-general] LogisticRegression to initiate SGDClassifier

2012-07-25 Thread Fred Mailhot
Hi all, I've got a text classification problem on which LogisticRegression consistently outperforms SGDClassifier(loss="log") by a few percentage points on the smallish [O(10^5) points] datasets I've been using for initial development/testing. The data set I'll ultimately be using for training is
