2 results about "Star schema" patented technology

The present disclosure relates to methods, systems, and apparatuses for featurizing time-series data to enhance machine learning model training. Time-series data, such as transaction records, is preprocessed to identify fields including descriptive and categorical information. Categories are assigned using a first machine learning model, and tags are applied based on domain-specific patterns or large language models. The processed data is organized into a star schema data structure comprising a fact structure and associated dimension structures. Features are generated from the data structure based on time windows, incorporating statistical metrics and identified patterns. These features are provided to a machine learning module to train a second machine learning model, improving accuracy and adaptability for applications such as customer behavior prediction and financial analysis. The disclosed approach addresses challenges of high dimensionality, noise, and temporal dependencies in time-series data, enabling robust and contextually relevant feature generation.

This invention discloses a method and apparatus for data fusion in process industries based on a star schema. The method includes the following steps: Step S1: Obtain a digitized process industry flowchart, identify objects, object attributes, and connection relationships in the flowchart using primitive recognition technology, and construct a graph structure model; Step S2: Assign a unique equipment code to each equipment node corresponding to each equipment object in the graph structure model, construct a star schema data association model centered on the equipment code, and perform data fusion by using different types of industrial data as association branches of the star schema data association model; Step S3: Based on the fused data of each equipment node in the star schema data association model, mark the status of each equipment node on the digitized flowchart to generate a holographic data view with status identifiers. This invention enables the fusion and display of different process industry data on a flowchart.
