Abstract: A deep learning model trained to learn to predict source code is tuned for a target source code generation task through reinforcement learning using a reward score that considers the quality of the source code predicted during the tuning process. The reward score is adjusted to consider code-quality factors and source code metrics. The code-quality factors account for the predicted source code having syntactic correctness, successful compilation, successful execution, successful invocation, readability, functional correctness, and coverage. The source code metrics generate a score based on how close the predicted source code is to a ground truth code.

Abstract: A method and device for provisionally determining the mass of a vehicle when it is initialized. After initialization of the vehicle, the method determines a vehicle mass value by a static mass determination method and then checks whether this value is within a predetermined tolerance band around the dynamically last-determined vehicle mass value, which has been stored for that purpose. If this is so, and there has in the meantime been no significant change of the vehicle's mass, the previously stored dynamic vehicle mass value is probably more accurate and is used in the determination. Otherwise it can be assumed that the vehicle mass value has changed substantially, and the statically determined vehicle mass value is therefore used until a device for the dynamic determination of a vehicle mass can supply a more accurate vehicle mass value after a short time.
