Abstract: A simulation test is run on a first machine learning model trained using first training data historically collected over a time period. The first training data includes a set of training inputs and a set of target outputs. In response to a determination that a result of the simulation test run on the first machine learning model satisfies one or more criteria, a size of the set of target outputs of the first training data is determined. Second training data for training a second machine learning model is obtained. A size of a set of target outputs of the second training data meets or exceeds the size of the target outputs of the first training data. The second machine learning model is trained using the second training data.

Abstract: Voice instant messaging between mobile and computing devices is described. In an embodiment, a messaging service receives a recorded voice clip from a mobile communication-enabled device via a wireless communication link. The messaging service then processes the recorded voice clip for communication via a data network to a computing-based device that renders an audio message from the recorded voice clip. A virtual connection protocol manages and sequences transmission control protocol (TCP) connection events to provide reliable wireless transfer of recorded voice clip(s) via wireless communication link. The mobile communication-enabled device logs a first instant messaging contact into the messaging service, and the computing-based device logs a second instant messaging contact into the messaging service to enable two-way voice instant messaging between the first instant messaging contact and the second instant messaging contact at the respective devices.
