  • Patent number: 11983646
    Abstract: Aspects of the subject disclosure may include, for example, system and apparatus that enable operations that may include receiving, by a processing system, project data defining a proposed machine learning (ML) project of an entity and storing the project data in a project database with other project data for other projects. The operations may further include extracting extracted features of the proposed project and, based on the extracted features, determining a clustering assignment for the proposed project. Determining the clustering assignment may comprise comparing information about the proposed project including the extracted features with information about the other projects and assigning the proposed project to a cluster including one or more projects having similar bias characteristics as the proposed project. The operations may further include determining a risk of potential bias for the proposed project and, based on the risk of bias, recommending a corrective action to reduce the risk of bias.

  • Publication number: 20230022673
    Abstract: Techniques for knowledge discovery based on indirect inference of association are presented. A data management component (DMC) can determine and extract, in a structured format, entities, relationships between entities, and concepts relating thereto in documents, based on analysis of information in the documents and/or keywords relating to concepts, to generate an association inference model. Using artificial intelligence techniques, DMC can embed the entities and relationships to a common representation to generate and train a scoring model that can be used to evaluate and score similarity strength between entities, including entities that do not have a known relationship, and can predict or infer relationships, including indirect relationships, between entities or between concepts. In that regard, DMC or user can evaluate concept-level scores to determine a level of relationship between concepts. DMC can feedback information from the scoring model or evaluation to update the association inference model.

  • Publication number: 20220350810
    Abstract: Techniques for determining, modifying, and correcting data elements of documents, tables, and databases are presented. A data management component (DMC) can determine and extract entities of a group of entities, and relationships between entities, in documents, tables, and databases based on analysis of the entities and information relating thereto. DMC can determine a trained model representative of the entities and their relationships based on the relationships. For a subsequently received entity, DMC can predict a relationship between the subsequent entity and an entity of the entity group based on the model. DMC can determine candidate data modifications associated with the subsequent entity based on the relationship between the subsequent entity and the entity. DMC can rank the candidate data modifications based on probabilities that the candidate data modifications are a correct data modification, wherein data modification information relating to the ranking can be presented as an output.
