Method and system for aggregation of semantic segmentation models

A system for aggregation of semantic segmentation models from multiple collaborators, the system comprising:

• an aggregator server;
• and
• a communication network to dispose the aggregator server in communication with each of the multiple collaborators,
• wherein the aggregator server is configured to:
• select, in batches, at least two collaborators from the multiple collaborators;
• receive corresponding semantic segmentation model information from each of the at least two collaborators;
• assign respective weight parameters to the semantic segmentation model information from each of the at least two collaborators;
• add controlled noise to the weight parameters for the semantic segmentation model information from each of the at least two collaborators;
• and
• generate an aggregated model based on the semantic segmentation model information using the weight parameters with the noise added thereto from each of the at least two collaborators.
