Either each machine could have its own ML model, in which case, however, the model would be unable to adapt to new environments. Or each machine could be trained on local data, which might not be sufficient to generate an optimal model. This is where federated learning comes into play: the machines are provided with a pre-trained model and then upload their data to the cloud, enabling a new model to be generated. This also allows new devices to be added and ensures that operations continue uninterrupted in the event of individual device failures.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-7 fusion_builder_column_1_2 1_2 fusion-flex-column\" style=\"--awb-bg-size:cover;--awb-width-large:50%;--awb-margin-top-large:20px;--awb-spacing-right-large:3.84%;--awb-margin-bottom-large:20px;--awb-spacing-left-large:3.84%;--awb-width-medium:50%;--awb-order-medium:0;--awb-spacing-right-medium:3.84%;--awb-spacing-left-medium:3.84%;--awb-width-small:100%;--awb-order-small:0;--awb-spacing-right-small:1.92%;--awb-spacing-left-small:1.92%;\"><div class=\"fusion-column-wrapper fusion-column-has-shadow fusion-flex-justify-content-flex-start fusion-content-layout-column\"><div class=\"fusion-text fusion-text-8\"><p style=\"font-weight: 400;\"><span style=\"color: #88cc05;\"><strong>What is the time commitment involved for the company in raising this objection?<\/strong><\/span><\/p>\n<p>The implementation of Federated Learning (FL) takes 3\u201312 months for planning, infrastructure, model development and data protection compliance.

Each client trained a model locally, with the individual loss values weighted by a custom-developed coefficient that took into account factors such as data quality, anomaly density and client trustworthiness. The weighted loss values were aggregated centrally to optimise a global model, which was subsequently evaluated for its effectiveness. A comparison with conventional aggregation methods showed that the weighted loss function achieved improved anomaly detection performance, particularly in heterogeneous and unbalanced data
