WebApr 26, 2024 · Soft margin SVM allows some misclassification to happen by relaxing the hard constraints of Support Vector Machine. Soft margin SVM is implemented with the help of the Regularization parameter (C). Regularization parameter (C): It tells us how much misclassification we want to avoid. – Hard margin SVM generally has large values of C. WebJun 8, 2015 · If I have an hyperplane I can compute its margin with respect to some data point.
