The more fault-tolerant the better
b is the deflection direction of the plane, w is the normal vector of the plane, and the mapping of x to the plane:
The first thing is to find the point with the smallest distance from the dividing line; then what kind of w and b are obtained, so that such a point has the largest value from the dividing line.
After scaling: 
; Take it as min again , that is, take yi*(w^T*Q(xi) + b) = 1 =>
