摘要:
A plurality of data keys are associated with a plurality of type values; query frequencies of the data keys are known. A computer memory is divided into a plurality of tranches, each tranche including a probabilistic or non-probabilistic data structure. The data keys are stored in the tranches in accordance with their query frequencies such that, e.g., frequently queried data keys are stored in data structures having higher accuracy and infrequently queried keys are stored in data structure having less accuracy (and consequently require less memory space).

Particular embodiments identify a search result in response to a search query issued by a user; select a web-based application based on the search query; construct a web page dynamically, the web page comprising: the search result; and a search container comprising an interface of the web-based application; and transmit the web page to a network device associated with the user for presentation to the user.

摘要:
A cardinality of an incoming data stream is maintained in real time; the cardinality is maintained in a data structure that is represented by an unsorted list at low cardinalities, a linear counter at medium cardinalities, and a PCSA at high cardinalities. The conversion to the linear counter makes use of the data in the unsorted list, after which that data is discarded. The conversion to the PCSA uses only the data in the linear counter.

Systems and methods are disclosed to enable delivering a contextually relevant action for an underlying focal point of a communication (an “entity”) between users over computing devices. Delivery of a contextually relevant action entails identifying the entity and associated descriptors or amplifying words in the communication surrounding the entity, reviewing databases of actions taken with respect to the identified entity and associated descriptors, reviewing the functions and features of platforms and applications supported on users' computing devices, computing correlations between the actions taken and entity involved and computing devices' available functions and features, and selecting a contextually relevant action from the computed correlation. The selected contextually relevant action is displayed simply as an executable action for a user to take or as a description of the entity or as a series of possible executable actions to take.

A method using weighted aggregated ensemble model for energy demand management of buildings includes initializing data values for integrated model to measure energy consumption, perform statistical analysis on data values to estimate accurate prediction, optimizing the data values using marine predator optimization for integrated model, analyze the output to minimize the mean square error and results show improvement in accuracy of integrated model. The data values comprise of σ, maximum number of splits, minimum leaf size, and λ. The weighted aggregated ensemble model for energy demand management of buildings shows best performance compared with other predictive models such as linear regression (LR), support vector regression (SVR), multilayer perceptron neural network (MLPNN), decision tree (DT), and generalized additive model (GAM).
