Access the `b` parametr in the SVC object of scikit learn

According to scikit learn's mathematical model of the SVC there is a parameter b (constant value of the model):

Yet in the SVC class documentation I don't see how can one access its value.

Is there a way to access it? Is it really used?
I wonder if I need to manually add a column of 1 to the data or the model has it built in.

Solution

  • b is not a parameter, it is a part of a solution. The model solves for w and b to find a separating hyperplane. I guess you don't need to worry about it.
