Abstract: There are proposed methods, devices, and computer program products for feature management. In the method, a first event associated with a first and a second object, and a second event associated with the first and second events are obtained, and a type of the first event is different from a type of the second event. A first feature of the first object is determined based on a first encoder, and a second feature of the second object is determined based on a second encoder. The first encoder is updated based on the first and second features and the first and second events. With these implementations, multiple events are used in determining the encoder for extracting the feature, and thus the encoder may have better performance in accuracy and increase performance of downstream tasks.
