  • Publication number: 20220292413
    Abstract: The present disclosure provides a bike sharing rebalancing optimization method based on an adaptive neighborhood search algorithm. First, based on a difference between locations of shared bikes and users' travel demands in temporal and spatial distribution, a bike sharing rebalancing model is constructed. Next, an adaptive neighborhood search algorithm is constructed by using an adaptive operator selection mechanism and based on the fusion of a large neighborhood search algorithm and a neighborhood search algorithm. Then, seven types of perturbation operators, six types of repair operators, and eight types of neighborhood search operators are designed based on features of rebalancing time, pickup-and-delivery actions, and a capacity limit of a vehicle. Finally, a termination condition is constructed such that the algorithm terminates at an appropriate time and an optimization solution for a rebalancing route is provided.

  • Patent number: 11423303
    Abstract: Apparatus and associated methods relate to providing a machine learning methodology that uses the machine learning's own failure experiences to optimize future solution search and provide self-guided information (e.g., the dependency and independency among various adaptation behavior) to predict a receiver's equalization adaptations. In an illustrative example, a method may include performing a first training on a first neural network model and determining whether all of the equalization parameters are tracked. If not all of the equalization parameters are tracked under the first training, then, a second training on a cascaded model may be performed. The cascaded model may include the first neural network model, and training data of the second training may include successful learning experiences and data of the first neural network model. The prediction accuracy of the trained model may be advantageously kept while having a low demand for training data.

  • Patent number: 11366920
    Abstract: Embodiments of the present disclosure provide systems and methods for defining database roles to allow sharing of the objects within a database in a more granular fashion. A database role is created within a database, and privileges are granted to the database role by a provider account. The database role may be granted to a share object, which would result in the share object being indirectly granted all privileges that have been granted to the database role. Once the share object has been hydrated in the consumer account, the local administrator can then decide which local roles are granted usage on the shared database role, thus ultimately allowing some level of filtering as to which shared objects can be accessed by which local roles.
