8. What is maximum margin hyperplane.
Margin of a separating line
To choose the “best” separating line, we introduce the concept of the margin of a
separating line. Given a separating line for the data, we consider the perpendicular
distances of the data points from the separating line. The double of the shortest
perpendicular distance is called the “margin of the separating line”.
Maximal margin separating line
The “best” separating line is the one with the maximum margin
The separating line with the maximum margin is called the “maximum margin line”
or the “optimal separating line”. This line is also called the “support vector machine”.
9. Define precision, recall and F-measure.
