Abstract: In one aspect of the present disclosure, the degree of side erasure occurring in neighboring tracks is controlled by controlling the skew angle of the tape head, relative to the longitudinal direction of motion of the tape past the head as a track is written. In one embodiment, the tape head is rotated relative to the longitudinal direction of tape travel, and the trailing edge of the tape head which forms an acute angle with the edge of a track being written, is used for writing tracks at a desired track pitch. Other aspects and advantages may be provided, depending upon the particular application.

Abstract: An environment includes one or more clients, a game mediator server, and a game server connected by a network. The clients include a game mediator and a game. The game server executes game playing sessions of the games. The game mediator server and the game mediators form a game mediation infrastructure to mediate game playing sessions. For example, the game mediation infrastructure creates “lobbies” for game playing sessions and enables clients connected to lobbies to communicate with one another. The games receive interactions at the client and communicate with the game server to impact execution of game playing sessions. The game mediator server sends deep links to clients, e.g., to initiate game installation, or to start the game at a particular portion of the game. The game mediation infrastructure may also enrich gameplay by customizing gameplay and/or the lobby, e.g. based on events that occur during execution of the game playing session, or locations of the clients.

Abstract: Within a multiplayer gaming environment, a game mediation infrastructure facilitates the creation and use of multiplayer gaming sessions. The game mediation infrastructure allows leveraging the context of an existing gameplay session within a game (e.g., the game being played, the identities of the participants) to begin a corresponding session in a game mediator application. The session in the game mediator application provides functionality—such as game-related communication capabilities—that is superior to that provided by the game itself. These actions by the game mediation infrastructure reduce or eliminate steps that would otherwise have to be performed by users, thereby greatly simplifying user coordination for multiplayer gaming.

Abstract: The present invention relates to metalearning of deep neural network (DNN) architectures and hyperparameters. Precisely, the present system and method utilizes Evolutionary Population-Based Based Training (EPBT) that interleaves the training of a DNN's weights with the metalearning of loss functions. They are parameterized using multivariate Taylor expansions that EPBT can directly optimize. Further, EPBT based system and method uses a quality-diversity heuristic called Novelty Pulsation as well as knowledge distillation to prevent overfitting during training. The discovered hyperparameters adapt to the training process and serve to regularize the learning task by discouraging overfitting to the labels. EPBT thus demonstrates a practical instantiation of regularization metalearning based on simultaneous training.
