What is SVG?SVG refers to a scalable vector graphic (
the normal vector of the plane.So the distance from the point to the plane is the distance that the vector of the point to the plane is projected on the normal vector of the plane.Since the separation plane we are considering is the plane where the positive and negative examples are correctly separated, the formula also needs to satisfy some properties:We requir
condition is as follows, the variable name here is not the same as ours, in order one by one corresponds to:Solution steps:1, fixed the alpha, to the W and b respectively to seek partial derivative, so that it equals 0:Bring back the previous L, get:The problem translates to:After that, the equation constraint is brought back to the formula, the extremum is obtained for each alpha-biased derivative, and then brought back to W and B to get the decision boundary.----------------------------------
draw vector images is the newly added canvas elements of SVG and HTML5. Both technologies Support Vector and grating graphs.
SVG Overview
Scalable Vector Graphics (SVG) is a language that uses XML to describe two-dimensional Graphics (SVG strictly follows the XML syntax ). SVG allows three types of graphics objects
