We all know the equation of a hyperplane is w.x+b=0 where w is a vector normal to hyperplane and b is an offset. To classify a point as negative or positive we need to define a decision rule. We can define decision rule as: If the value of w.x+b>0 then we can say it is a positive point otherwise it is a negative point. Now … See more SVM is a powerful supervised algorithm that works best on smaller datasets but on complex ones.
