Please predict whether this patent is acceptable.PATENT ABSTRACT: Training data is collected describing multiple past messages sent over a computer-implemented communication service. For each of the past messages, the training data set comprises a record of a respective channel of the respective message, and a record of respective feature vector of the respective message, wherein the channel corresponds to a respective one or more recipients to which the respective message was sent, and wherein the feature vector comprises a respective set of values of a plurality of parameters associated with the sending of the respective message. The training data is used to train a machine learning algorithm. By applying the machine learning algorithm to the feature vector of a respective subsequent message, to be sent by a sending user over the computer-implemented communication service, a prediction is generated regarding one or more potential recipients of the subsequent message.
