This paper introduces a Python-based federated learning framework and presents a method for automatically converting federated learning algorithms built on the framework into Communicating Sequential Processes (CSPs) using ChatGPT. While manual conversion was previously required, ChatGPT automates the process, increasing efficiency. The converted CSP processes are then verified for safety and liveness using the PAT model verifier. Experiments demonstrate successful conversion and validation for both centralized and distributed federated learning algorithms.
