7 results about "Denormalization" patented technology

Denormalization is a strategy used on a previously-normalized database to increase performance. In computing, denormalization is the process of trying to improve the read performance of a database, at the expense of losing some write performance, by adding redundant copies of data or by grouping data. It is often motivated by performance or scalability in relational database software needing to carry out very large numbers of read operations. Denormalization should not be confused with Unnormalized form. Databases/tables must first be normalized to efficiently denormalize them.

Multi-scale time series prediction method based on adaptive sparse expert selection strategy and closed continuous time neural network

The invention discloses a multi-scale time sequence prediction method based on an adaptive sparse expert selection strategy and a closed continuous time neural network. The method comprises the following steps: carrying out normalization and low-dimensional feature mapping based on RevIN; performing trend-seasonal structure enhancement processing on the feature sequence after linear mapping; constructing a multi-scale expert model based on the feature sequence after trend-season enhancement; self-adaptive sparse expert selection and load balancing loss calculation are carried out; carrying out weighted aggregation and residual fusion on multi-scale expert output; global modeling of a closed continuous time neural network based on channel weighting is carried out; and finally performing prediction generation and reverse normalization. The multi-scale time series prediction method has the multi-time-scale adaptive modeling capability, the sparse expert efficient selection mechanism and the global continuous time modeling capability, and can be applied to various multivariable time series prediction scenes such as power load prediction, weather prediction, industrial production monitoring, traffic flow prediction and financial price prediction.

Aggregation framework system architecture and method

A system and computer implemented method for execution of aggregation expressions on a distributed non-relational database system is provided. According to one aspect, an aggregation operation may be provided that permits more complex operations using separate collections. For instance, it may be desirable to create a report from one collection using information grouped according to information stored in another collection. Such a capability may be provided within other conventional database systems, however, in a non-relational database system such as NoSQL, the system is not capable of performing server-side joins, such a capability may not be performed without denormalizing the attributes into each object that references it, or by performing application-level joins which is not efficient and leads to unnecessarily complex code within the application that interfaces with the NoSQL database system.

Cloud-Based, Context-Aware, Independent GenAI Models as a Loose Confederation

Systems and methods address the inefficiencies in document creation and management within large, globally dispersed organizations. The system leverages multiple independent cloud-based Generative AI (GenAI) models, each specialized and context-sensitive, to dynamically generate and contextualize documents tailored to specific regional and contextual requirements. A global repository meticulously catalogs and annotates documents with detailed metadata, enabling precise retrieval based on user-specific search criteria. The system employs a denormalization slant to generalize search queries, facilitating global context searches and affinity mapping to ensure relevance. A Primary Context Controller Hyper Model orchestrates the confederation of independent GenAI models, refining and enhancing documents to meet precise user needs while adhering to local nuances. Automated, rule-based approvers ensure instant validation and quality control, while a feedback loop mechanism continuously improves the models' accuracy and relevance. This decentralized, scalable approach reduces computational burden and costs, providing a robust, efficient solution for high-quality, context-aware document generation.
