What does this sentence in the programming assignment mean -:
The lines represent ‘equal distance’ boundaries where the distance between center points is equal.
(in multi-class classification section)

2

It means that:

  1. you locate the center point of each of the groups
  2. pick any two center points out
  3. draw a line to connect the two points
  4. at the mid-point of the line, draw a perpendicular line that goes through the mid-point
  5. that perpendicular line is a boundary line.
