  • Publication number: 20230316037
    Abstract: The present invention relates to systems and methods for training artificial intelligence assets. The system comprises a digital market module that facilitates the acquisition of a bot from a digital market. A game module enables a user to play a game using the acquired bot. A training module is configured to train the bot through game play against one or more players, employing a mimicry technique. A feedback module obtains training data on the bot's performance in the game, capturing characteristics of the game play, and stores the data in metadata or a database. The system offers an efficient and effective approach to train artificial intelligence assets in the context of gaming, allowing for improved performance and adaptability based on real-time user interactions.

  • Publication number: 20230313561
    Abstract: The present invention relates to a locking device 1 having a deadbolt 104 within a casing 102, which deadbolt 104 is movable between an advanced position wherein it protrudes from a front face of the casing 102 and a retreated position, wherein it is retracted into the casing 102. The locking device 1 comprises: a link plate 130 which moves the deadbolt 104 to the advanced position; a deadbolt blocking member 110 which is moveable between a blocking position blocking the deadbolt 104 in the advanced position and an unblocking position to allow the deadbolt 104 to move to the retreated position; an electrically driven actuator unit 120 which moves the deadbolt blocking member 110 between the blocking position and the unblocking position; and a control circuit configured to control the electrically driven actuator unit 120 so that once the deadbolt 104 is moved to the advanced position, the deadbolt blocking member 110 is moved to the blocking position by actuation of the electrically driven actuator unit 120.

  • Publication number: 20230310078
    Abstract: An electrosurgical apparatus and method for performing thermal treatment in the gastrointestinal tract, e.g. to ablate duodenal mucosal tissue. The apparatus comprises an instrument having a flexible cable and an applicator suitable for use with a gastroscope, which can be deployed within a patient to delivery energy in a targeted or otherwise controllable manner. The applicator can deliver microwave energy by radiation. The direct and depth-limited nature of microwave energy can be make it more effective than treatments that rely on thermal conduction. The applicator may include a radially extendable portion arranged to move an microwave energy delivery structure into contact with duodenal mucosal tissue at the treatment region. The applicator may comprise any of a balloon, bipolar radiator, movable paddle, and rotatable roller element.

  • Publication number: 20230316065
    Abstract: Embodiments described herein are directed to training techniques to reduce the power consumption and decrease the inference time of an NN. For example, during training, an estimate of power consumed by AMACs of a hardware accelerator on which the NN executes during inferencing is determined. The estimate is based at least on the non-zero midterms generated by the AMACs and the precision thereof. A loss function of the NN is modified such that it formulates the non-zero midterms and the precision thereof. The training forces the modified loss function to generate a sparse bit representation of the weights of the NN and to reduce the precision of the AMACs. Noise may also be injected at the output of nodes of the NN that emulates noise generated at an output of the AMACs. This enables the weights to account for the intrinsic noise that is experienced by the AMACs during inference.
