title: How does sklearn.svm.svc's function predict_proba() work internally?
body: <p>I am using <a href="http://scikit-learn.org/stable/modules/generated/sklearn.svm.SVC.html" rel="noreferrer">sklearn.svm.svc</a> from <a href="http://scikit-learn.org/stable/" rel="noreferrer">scikit-learn</a> to do binary classification.  I am using its predict_proba() function to get probability estimates.  Can anyone tell me how predict_proba() internally calculates the probability?</p>
