  • Patent number: 11586528
    Abstract: An improved SDK includes a set of APIs and a crash handler registered with the operating system. Each API is an interface accessible by a computer software application. Up on entrance, each API determines the current thread identifier, and inserts it into a list if it is not already in the list. Each thread identifier corresponds to an API call counter, which is incremented by one at the entrance and decremented by one at the exit point of the API. The SDK also records the identifier of the thread it creates for callback functions. When a crash occurs, the crash handler is executed. It determines that the crash is related to a callback interface if the crash thread identifier matches the callback thread identifier. The crash is determined to be caused by the SDK if the API call counter corresponding to the crash thread identifier is greater than zero.

  • Publication number: 20230036720
    Abstract: Aspects of the disclosure provide for controlling an autonomous vehicle using no block costs in space and time. For instance, a trajectory for the autonomous vehicle to traverse in order to follow a route to a destination may be generated. A set of no-block zones through which the trajectory traverses may be identified. A no-block zone may be region where the autonomous vehicle should not stop but can drive through in an autonomous driving mode. For each given no-block zone of the set, a penetration cost that increases towards a center of the no-block zone and decreases towards edges of the no-block zone may be determined. Whether the autonomous vehicle should follow the trajectory may be determined based on the penetration cost. An autonomous vehicle may be controlled in the autonomous driving mode according to the trajectory based on the determination of whether the autonomous vehicle should follow the trajectory.

    Abstract: The present disclosure discloses a chess self-learning method and device based on machine learning, a move selection output layer and a value evaluation output layer of the method share the same input layer and hidden layer of a neural network, and a Monte Carlo tree search tree is used to construct a strategy optimizer. The training process of the method is divided into two parts, namely data generation and neural network training, so that an error between a value scalar outputted by a neural network and a final result of self-play is as small as possible, and a move vector outputted by the neural network is as close as possible to a decision vector given by a Monte Carlo tree for each search step. The present disclosure aims to construct an Al chess player for people to play chess.
