Aspects of the invention include a computer-implemented method that receives, by a processor, an ensemble decision tree and generates, by the processor, native code from the ensemble decision tree. The method compiles, by the processor, the native code into machine language and scores, by the processor, the execution time of the native code. The method dynamically reoptimizes, by the processor, portions of the native code corresponding to the most traversed portion of the ensemble decision tree.

Systems, methods, and computer-readable media for generating group-based sequential point-of-interest (POI) recommendations are disclosed. A primitive graph or sparse transition matrix is constructed that represents relationships between users, between POIs, and between users and POIs. A loss data prediction algorithm is executed on the primitive graph to obtain a filled graph, which may be a filled user-POI bipartite graph. A group sequential recommendation engine then performs an iterative sequential recommendation process that involves performing, at each iteration, various manipulations on the filled graph to obtain first a homogenous node type graph and then a minimum spanning tree. A next POI to recommend in a sequence of POIs is then determined from the minimum spanning tree. The iterative process continues until stopping criteria is met.

The present disclosure provides a widget displaying method and apparatus, and a storage medium, which pertain to the field of flexible display technology. The method comprises: acquiring pressure bearing capacity information of the flexible display device, the pressure bearing capacity information indicating pressure bearing capacities of a plurality of areas on the flexible display device; determining a force bearing area on the flexible display screen, based on the pressure bearing capacity information; and displaying a touchable widget, based on the force bearing area. The present disclosure addresses the problem that the flexible display device bends under gravity, which makes it difficult for the user to perform touch operations on the flexible display screen, and achieves the effect that a touchable widget can be displayed on an area with a high pressure bearing capacity, thereby ensuring the stability when the user performs touch operations on the flexible display device and improving success rate and accuracy of the touch operations.

This invention relates to the Internet of Things (IOT), and discloses a method and apparatus of data filtering in the IOT, where the IOT includes a plurality of sensor devices. The method includes: inputting an application deployed rule; converting the rule into at least one sub-predicate expression having static predicates and dynamic predicates; inputting data collected by the sensor devices; matching the collected data with the static predicates and the dynamic predicates of the sub-predicate expression in sequence; and distributing matched data to the application. In this invention, a rule is divided into static and dynamic predicates, and a match is performed on static predicates before dynamic predicates, so that the speed of predicate match can be improved and fast and efficient data filtering in the IOT can be achieved.
