  • Publication number: 20260099763
    Abstract: Mechanisms are provided for performing an artificial intelligence (AI) model explainer for an AI computer model. The mechanisms receive input data comprising non-numeric feature data, which may be results generated by the AI computer model. The mechanisms process the non-numeric feature data via a first computer model trained to convert non-numeric feature data into a numeric representation of the non-numeric feature data. The mechanisms input the numeric representation of the non-numeric feature data into the AI model explainer to generate an AI model explanation output having a portion corresponding to the numeric representation of the non-numeric feature data. The mechanisms process the AI model explanation output via a second computer model that is trained to convert the portion from the numeric representation to an output non-numeric representation consistent with the non-numeric feature data and the converted output may then be output.

  • Patent number: 12147330
    Abstract: In an approach for smart test data workload generation, a processor receives a plurality of expected image frames for a user interface application to be tested. The plurality of expected image frames is pre-defined and represents a series of workflows and operations of the user interface application to be expected based on a design requirement. A processor calculates a first set of hash-values for each corresponding expected image frame. A processor samples the user interface application with a frequency to a plurality of testing image frames during a test run on the user interface application. A processor calculates a second set of hash-values for each sampled testing image frame. A processor compares the first set of hash-values to the second set of hash-values. A processor verifies that the second set of hash-values matches the first set of hash-values.

  • Patent number: 12105722
    Abstract: Provided are techniques for building and using a sparse Time Series Database (TSDB). Time series records are received from a native TSDB, where each of the time series records includes a timestamp and one or more tags. Timeslots are determined for shards for the sparse TSDB based on the timestamp included in each of the time series records. The sparse TSDB is built by creating the shards for the determined timeslots and storing the time series records in the shards, while filling in empty ranges in the shards. A query that specifies at least one of the one or more tags is received. It is determined whether to execute the query against the sparse TSDB, and, in response to a determination to execute the query against the sparse TSDB, the query is executed against the sparse TSDB to generate results that are returned.
