  • Publication number: 20230401258
    Abstract: This application relates generally to intelligent and explainable link prediction in knowledge graph systems that automatically incorporate user feedback. In one aspect, this application discloses an iterative process for predicting a link set as a group of links in a knowledge graph in an embedding space by expanding the knowledge graph with predicted and validated single links in each iteration such that a final set of links are predicted with each one being added to the set depending on previously added predicted links. In another aspect, this application also discloses automatically extracting rules from user feedback of link predictions and generating a user feedback knowledge graph from the extracted rules, which in combination with an original knowledge graph are used for the generation of the link predictions.

  • Publication number: 20220367051
    Abstract: Methods and systems for estimating causal effects from knowledge graphs are provided. The method includes obtaining intervention application data and subject history data for a candidate group of subjects, and dividing, based on the intervention application data, the candidate group into a reception subgroup that received an intervention and a rejected subgroup that did not receive the intervention. The method includes for each subject within the candidate group, mapping, based on the subject history data, a covariate value set onto a knowledge graph with an embedding neural network; and for each subject in the reception subgroup or the rejection subgroup, translating the covariate value sets for the subjects within the reception subgroup or the rejection subgroup into a reception matrix or a rejection matrix with a feature neural network. The method includes comparing the reception subgroup to the rejection subgroup to determine a differential intervention effect.

  • Patent number: 11386335
    Abstract: Complex computer system architectures are described for analyzing data elements of a knowledge graph, and predicting new facts from relational learning applied to the knowledge graph. This discovery process includes converting the knowledge graph into a set of candidate embeddings spaces to apply further analysis to rank the set of candidate embeddings spaces, where the top ranked candidate embeddings spaces are further processed to identify the new facts.

  • Publication number: 20220180225
    Abstract: A device may receive data associated with units of a group. A subset of the data, for a unit, may include values for features of the unit and an indication of whether the subset indicates that the unit satisfies a qualification threshold of a qualification model. The device may identify subsets of the data that indicate that a subsets of units do not satisfy the qualification threshold; alter feature values, of the subsets of the units, for a feature to generate revised subsets of the data; and process, based on the qualification model, the revised subsets of the data to obtain counterfactual explanations. The device may determine an impact score associated with the feature based on a quantity of units, of the subset of units, that satisfied the qualification threshold based on the revised subsets of the data; and determine that the impact score satisfies an impact threshold.

  • Publication number: 20220138632
    Abstract: A device may receive calibration data associated with a plurality of units and receive a set of rules; determine, based on the set of rules, a plurality of groups associated with the plurality of units; and process the calibration data based on a pretrained artificial intelligence (AI) model. The device may determine, based on processing the calibration data, a prediction that is associated with a group of the plurality of groups; and determine, based on the set of rules, a target associated with the group based on the set of rules. The device may generate a calibration model based on the prediction and the target, and aggregate the calibration model with another calibration model that is associated with another group of the plurality of groups to form a calibrated AI model.
