| Bounding Support Vectors |
A support vector machine (Section 18.20) identifies a linear separator between observations that belong to different classes. If the observations are not tagged with a class then the algorithm can be utilised to identify a bounding region for the training dataset. The model is then represented as the boundary support vectors.
No all observations from the training dataset will sit within the boundary. That is, not all observations will fit the model. Such observations we might consider as outliers.
