SVC Parameters When Using RBF Kernel Chris Albon

Dec 20, 2017· C The Penalty Parameter. Now we will repeat the process for C: we will use the same classifier, same data, and hold gamma constant. The only thing we will change is the C, the penalty for misclassification.. C = 1. With C = 1, the classifier is clearly tolerant of misclassified data point.There are many red points in the blue region and blue points in the red region.

No Fear of Machine Learning how to classify text in less
