Question
Consider the dataset with six datapoints: , where , , , , , and the labels are given by , and . A hard margin linear support vector machine is trained on the above dataset.Which ONE of the following sets is a possible set of support vectors?
Correct answer
(D) \x₁, x₂, x₃, x₄\
Solution
A hard margin linear SVM seeks to find a hyperplane that maximizes the margin subject to the constraints for all . The support vectors are the points for which the equality holds.Given the datapoints:
- Class ():
- Class ():
- For : (Equality holds Support Vector)
- For : (Equality holds Support Vector)
- For :
- For : (Equality holds Support Vector)
- For : (Equality holds Support Vector)
- For :
