Hello!  
I am very new to Flower framework. I want to know if we can implement k-anonymity on a few clients and local differential privacy on the others with different values of parameters using Flower.  
If yes, if someone could please explain how can I do that.  
Thanks

Hey, thanks for the question.

Yes, it is possible. First, you need to define your clients and partition their data. For clients where you want to implement k-anonymity, apply it to their data before using it for training. Additionally, for clients where you want to use Local DP, utilize the existing mod.

Can you share some example where Local DP has been used with Flower? Can this run on Colab Notebook?
