# The source class. CLASS_NUM = 4

Hello,

Thank you for your outstanding work on the FL defense mechanisms. I'm currently in the process of reproducing your implementation to gain a deeper understanding of how these defenses function.

While successfully running the code on my local machine, I encountered a specific line in the defense.py file that I'd appreciate clarification on. Line 36, which sets the value of CLASS_NUM within the source class to 4, left me uncertain about its exact purpose.

If you have a moment, I would be incredibly grateful if you could provide some insight into the meaning and rationale behind this line of code.

Thank you for your time and consideration.
