I want a full detailed implementation of a paper titled "Federated Learning of User Authentication Models"

hello, I need the mentioned paper's algorithm fully implemented from scratch using the same dataset in the paper, I have a 100% understanding of the paper's algorithm, but I do not have the skills to implement it myself thus I require your assistance, The paper discusses federated learning and user authentication thus I need someone with experience in both, the code also deals with federated averaging and deep learning.

before proceeding to work with you I need you to:
- give me a thorough explanation of the paper's algorithm so that I know that you are going to implement it correctly as I am on a short timeline.

I would also like to stay posted on the process by viewing the segments you have implemented every 5 days.

pleased to working with you, I have a budget of 700USD
