![]() Later on in Section 3, let us derive the same formula using two mathematical optimization methods. In other words, we can say that the distance between point and plane is the length of the normal vector dropped from the given point onto the given plane. Let us rst derive the formula for the shortest distance using four elementary and familiar methods (Section 2). The distance between point and plane is the length of the perpendicular to the plane passing through the given point. Further let xp be the projection of x on the. that the perpendicular distance d l(PB)(seetheFigure)isthe shortest distance between point P and line L. Where $\nabla h(x) = (\partial h(x)/\partial x_1,\ldots,\partial h(x)/\partial x_n)\in\mathbb. Distance of a Point to the Hyperplane Consider a point x Rd, such that x does not lie on the hyperplane. The distance between point and plane is the shortest perpendicular distance from the point to the given plane and is given by, Axo Byo Czo D/(A2 . Separating line will be defined with the help of these data points. ![]() $$(i)\ \ \nabla f(x) = \lambda\nabla g(x) $$ Support Vectors Datapoints that are closest to the hyperplane is called support vectors. The Kuhn-Tucker formulation of this problem is specified by the following equations: In section three is studied the distance between point and hyperplane and are reminded the particular cases in Euclidean spaces R2. ![]() According to your notation, you can tackle the problem trying to minimize the objective function $f(x) :=(x-x_0)^T (x-x_0)$, i.e., the square of the Euclidean distance between $x$ and $x_0$, subject to the equality constraint $g(x) := w^Tx - b = 0$, i.e., $x$ belongs to the hyperplane. ![]()
