I was trying to implement the USD algorithm (Paper Tile: Discretization oriented to Decision Rules). However, I have some doubts:
1. At line 20 of the algorithm it is written that Ii has the same majority class than Ii+1. What is the meaning of this?
2. At line 20 of the algorithm it is written that there is a tie in Ii or Ii+1. A tie of what?
3. What is the requirement of line number 14 & 15 when line number 11 & 12 is covering all consecutive intervals?
