| double | m_C |
| Regularization parameter. The exact meaning depends on the sub-class, but the value is always positive, and higher implies a less regular solution. | |
| bool | m_trainOffset |
| Is the SVM trained with or without bias? | |
| bool | m_unconstrained |
| Is log(C) stored internally as a parameter instead of C? If yes, then we get rid of the constraint C > 0 on the level of the parameter interface. | |
