SGDClassifier accuracy MUCH worse than LinearSVC

Image
1 $begingroup$ with LinearSVC, I get an accuracy off 0.89: linearSVC = LinearSVC().fit(X_train, y_train) y_pred = linearSVC.predict(X_test) print('accuracy', np.sum(y_pred == y_test) / y_test.shape[0]) Because I need online training, I tried the same with SGDClassifier: sgd = SGDClassifier().fit(X_train, y_train) y_pred = sgd.predict(X_test) print('accuracy', np.sum(y_pred == y_test) / y_test.shape[0]) but now I get 0.004 - what am I missing here? The shape of X_train is (21519, 8255). Of course I do not expect the exact same accuracy, but SGDClassifier basically gets nothing right... scikit-learn online-learning share | improve this question

Short story: Political story, San Francisco wins drawing for deciding morals

Image
2 I think the short story is circa 2005 or so, a time when society has agreed to determine political and moral policy through a lottery system, spinning a wheel - definitely a Wheel of Fortune motif. It is told from a conservative point of view, and at the end San Francisco is awarded morality laws. I think I read it in S&SF or Asimov's or Analog at that time. The protagonist is a critical person attending the drawings, and conservative cities begin "winning" control of different political topics, such as birth control, guns, freedom of speech. story-identification short-stories share | improve this question edited yesterday
