The equation of a plane with normal vector passing through the point is given by (4) For a plane curve, the unit normal vector can be defined by (5) where is the unit tangent vector and is the polar angle. Given a unit tangent vector (6) with , the normal is (7) ...
We want to create as broad a separation (a wide "street") between positive and negative examples, or in other words, maximize the distance between the tips of the support vectors and the decision boundary (the median of the street): If the normal vector to the decision hyperplane, w⃗ ...
Normal vectors of a Curve Definition: at a point where κ≠0, the principal unit normal vector for a smooth curve in the plane is N=1κdTds. 关于,N 我们知道以下几点: 1、 ∵r⋅drdt=0∴N⋅T=1κ(dTds⋅T)=0, 即和N和T 相互垂直。 2、 1κ系数使得 N 也成为单位向量。 3、 ...
