Plotting the separating plane
September 16, 2006 01:49AM
Hi

for the Exam guidelines question 1.4 I get the final weight vector
[2,0,0] with the threshold value 2.

I can draw the diagram of the input values but do not understand how to plot the separating plane.

Anyone who knows please help?

Hi,
the separating plane is the plane with equation w.x = threshhold
i.e W is the norm vector and a point can be obtained from the above equation
ex:
(2,0,0).(x,y,z)=2 <=> 2x=2
the norm vecor is (2,0,0) and a point by which the plane passes is:
(1,0,0)

hope this helps...

Hi,

Thanks for the explanation - but can you also show how to get the other points of the plane? I know the one point goes through the 0 origin

what I dont understand is what is 'x' in w.x = threshold.

Hi,
once you have the equation you can get as much points as you want, just take some values for x and y then get the z value (in 3D case)
for example,
3x+2y+z=0
take x=1, y=0
you get z = -3 so you got the point (1,0,-3)
as for w.x=treshhold, the x means the input vector. i.e. x=(x,y,z) (the first x should be in bold for the vector)
