Classifying an instance using machine learning

A selection server for selecting one or more other communications devices for classifying an instance using Machine Learning, ML, the selection server being operative to:

• receive, from a communications device for classifying an instance using ML, a selection request message for selecting one or more other communications devices for classifying an instance using ML, the selection request message comprising information pertaining to at least one of:
• an identity of a user of the communications device, a contact list of the user, a type of data comprised in a feature vector representing the instance, an origin of the feature vector, a classification of the instance using a local first ML model of the communications device, a location of the communications device, a location associated with the instance, and one or more classified instances which are related to the instance represented by the feature vector;
• select the one or more other communications devices based on at least one of:
• the identity of the user, the contact list of the user, the type of data comprised in the feature vector, the origin of the feature vector, the classification of the instance using the local first ML model, the location of the communications device, a respective location of the one or more other communications devices, the location associated with the instance, and the one or more classified instances which are related to the instance represented by the feature vector;
• and
• transmit, to the communications device, a selection response message comprising information identifying the selected one or more other communications devices.
