  • Patent number: 12619613
    Abstract: A system and method are provided for feature engineering. The method may include obtaining data from a plurality of data sources. The method may also include generating, based on the data, features for training machine learning models using a single data pipeline that uses a feature generation logic that is separate from an execution logic. The method may also include generating, based on relations and/or joins in the feature generation logic, metadata for explaining the features, and generating, based on the metadata, lineage information representing a mapping of one or more features to intermediate tables and/or input tables. The method may also include displaying the lineage information representing the mapping, including allowing a user to select and/or drill down different features, intermediate tables and/or input tables. The method may also include storing the features and the metadata for the features to a feature store.

  • Patent number: 11121932
    Abstract: A data model can be customized by a user and executed in real-time at a network device. The user provides definitions for the customized data model based on a data model locally stored on the network device. The user provided definitions are used to generate a mapping contract which is processed by a mapping package generator to generate a mapping package. The mapping package can then be processed by a translation engine to dynamically execute a customized data model in real-time.

  • Patent number: 8111611
    Abstract: Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with Bidirectional Forwarding Detection (BFD) on multilink bundled interfaces. A packet switching device communicates with another packet switching device through a multilink bundled interface configured for communicating over a plurality of bundled communication links. A separate BFD session is conducted over each link of the multiple bundled communication links, and in response to a BFD-detected failure condition, the use of the one or more links or the entire bundled interface is removed from service.

  • Patent number: 6745179
    Abstract: A system for facilitating viewer navigation through online information relating to chemical products is provided. The system includes a server in communication with at least one database; a link to an order fulfillment system; a link to a payment processing system; and a rink to a client system. The system is executing web server and application server software; a commerce tool for ordering one or more chemical products; database management and security tools; and a navigation tool. The navigation tool includes a user interface displaying objects relating to the chemical products in a form of a periodic table. Each objects is linked to information or services concerning the chemical products and each object is represented as an abbreviation of a function provided by the navigation tool.

  • Publication number: 20030071841
    Abstract: An exemplary embodiment of the invention relates to a method and system for facilitating viewer navigation through online information utilizing a metaphorical representation of a periodic table of elements. The system comprises a server in communication with at least one database; a link to an order fulfilment system; a link to a payment processing system; and a link to a client system. The system is executing software including web server and application server software; a commerce tool; and database management and security tools. The system is also executing a navigation tool that includes a user interface displaying objects metaphorically simulating a periodic table of elements. The objects are linked to functions provided by the navigation tool. The invention also includes a method for navigating within a graphical user interface of a computer system over a network.
