Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for intelligently buffering queries from a mobile application. In one aspect, the method may include receiving, by an application programming interface executing on a mobile device, multiple queries, from different software widgets executing on a mobile application, for data from a database stored on the mobile device, determining, by the application programming interface, a level of priority for each query of the multiple queries, providing, by the application programming interface, each of the multiple queries for storage in a data buffer until processing resources of the mobile device are available to process one or more of the multiple queries, and processing each query of the multiple queries against the database stored on the mobile device based on the assigned level of priority.

Abstract: In an example embodiment, a solution is provided in which an outbox table is added to each container in a database. Rather than perform an emit solely using the application instance alone (in response to a notification from the database that the underlying database action has been performed), or using an outside outbox table processor, an outbox table processor is integrated into the microservice application. When a database action is performed by the microservice application, that database action is written into the outbox table in the corresponding container in the database. Furthermore, whenever the outbox table processor determines that the state of the database has changed in a way that leads to an emit, it then reads the actions in the outbox table, issues an emit to notify one or more external systems of the actions, and deletes those actions from the outbox table.

Abstract: A method for automatically selecting input for a smart city application includes determining data schema for a data lake locally stored at a local smart city platform instance and determining aggregate statistical information of data corresponding to a data schema concept. The determined data schema and aggregate statistical information are sent to a global matcher with an identifier of the application. An input matching is received, from the global matcher, for the application, wherein the input matching provides, for each respective input of the application, a respective data schema concept. Data corresponding to the respective data schema concept for each respective input of the data-driven application is provided as input to the application. The input matching is determined using a trained quality of service (QOS) scoring function trained to minimize a QoS error of aggregated QoS scores against a ground-truth QoS score computed from predictive accuracy and/or user feedback.

Abstract: The present disclosure provides a multi-task deep Hash learning-based retrieval method for massive logistics product images. According to the idea of multi-tasking, Hash codes of a plurality of lengths can be learned simultaneously as high-level image representation. Compared with single-tasking in the prior art, the method overcomes shortcomings such as waste of hardware resources and high time cost caused by model retraining under single-tasking. Compared with the traditional idea of learning a single Hash code as an image representation and using it for retrieval, information association among Hash codes of a plurality of lengths is mined, and the mutual information loss is designed to improve the representational capacity of the Hash codes, which addresses the poor representational capacity of a single Hash code, and thus improves the retrieval performance of Hash codes.

The method requires minimal manual input and is a fast, simple, resilient and low-code/no-code technique that can be extended to support any type of calculation code and calculation specifications with minimal or no change.

Abstract: The present invention relates to an implementation method for graphic-blockchain-orientated hybrid consensus, at least comprising: calling at least one module to generate a new data block and broadcast it; calling at least one module to check and validate the received new block based on predetermined rules; calling at least one module to generate a void block; and calling at least one module to update a committee member list. The existing graphic blockchain can only achieve probabilistic consensus, yet the present invention achieves deterministic consensus on graphic blockchain for the first time, thereby reaching consensus faster. The present invention decouples generation and consensus of blocks for the first time, so that the two parts can be designed separately in a modularized manner. The present invention provides the first totally decentralized hybrid consensus algorithm in the graphic blockchain. This is unachievable to many existing graphic blockchain such as IOTA and Obyte.
