Before revision:  In the experiments, Fed-NILM is validated on two real-world datasets . Besides, a comparison of Fed-NILM with locally-trained NILMs and the centrally-trained one is conductedin both residential and industrial scenarios .
After revision:  Experiments based on two measured load datasets are conducted to explore the generalization ability of Fed-NILM is validated on two real-world datasets . Besides, a comparison of Fed-NILM with locally-trained NILMs and the centrally-trained one is conductedin both residential and industrial scenarios .
