The image depicts a line chart titled Federated Transfer Learning Loss Over Rounds. The X-axis is labelled Rounds and shows values from 1 to 20. The Y-axis is labelled Loss and shows values ranging from approximately 0.35 to 0.80. The plotted line labelled F T L Loss starts at about 0.80 at round 1, decreases to around 0.70 by round 3, shows a slight increase to about 0.70 at round 5, and then continues to decline steadily. The loss reaches approximately 0.60 at round 7, about 0.50 at round 11, and gradually decreases further to around 0.35 by round 20, indicating overall reduction in loss across successive training rounds.Threat detection loss for the global server node
