WebFeb 28, 2024 · Calculating the value of. b. ∗. in an SVM. In Andrew Ng's notes on SVMs, he claims that once we solve the dual problem and get α ∗ we can calculate w ∗ and consequently calculate b ∗ from the primal to get equation (11) (see notes) I am not sure how this was derived from the primal. The generalized lagrangian is (see equation 8 ... WebSVM without the addition of slack terms is known as hard-margin SVM. 1. ...
