Patent number: 11922279Abstract: An approach for selecting a transformed prediction model for estimating the uncertainty of prediction associated with machine learning is disclosed. The approach determines a function corresponding to a prediction interval based on one or more datasets and calculates one or more sets of prediction interval parameters associated with the function based on training a set of regression models with the one or more datasets. The approach creates one or more transformed predictions based on the one or more sets of parameters and based on a logical distance and selects a transformed prediction model based on a mean absolute correlation from the one or more transformed predictions. Furthermore, the approach outputs the selected transformed prediction model.Type: GrantFiled: June 12, 2020Date of Patent: March 5, 2024Assignee: International Business Machines CorporationInventors: Wojciech Sobala, Rafal Bigaj, Lukasz G.

Patent number: 11790256Abstract: A computer-implemented method, system and computer program product for analyzing test result failures using artificial intelligence models. A first machine learning model is trained to differentiate between a bug failure and a test failure within the test failures based on the failure attributes and historical failures. The failure type for each failed test in test failure groups is then determined using the first machine learning model. The failed tests in the test failure groups are then clustered into a set of clusters according to the failure attributes and the determined failure type for each failed test. A root cause failure for each cluster is identified based on the set of clusters and the failure attributes. The root cause of an unclassified failure is predicted using a second machine learning model trained to predict a root cause of the unclassified failure based on identifying the root cause failure for each cluster.Type: GrantFiled: July 22, 2022Date of Patent: October 17, 2023Assignee: International Business Machines CorporationInventors: Lukasz G Cmielowski, Maksymilian Erazmus, Rafal Bigaj, Wojciech Sobala

Patent number: 11704220Abstract: An overall performance metric of a computer system may be determined for each bin of the set of analysis bins. In case one or more bins of the set of analysis bins do not have at least a predefined minimum number of records, a new set of analysis bins may be redefined by joining analysis bins of the set of analysis bins. For each bin of the redefined set of bins a machine learning (ML) performance metric of the ML model may be computed. The ML performance metric may be estimated for the set of analysis bins using the ML performance metrics of the redefined bins. The computer system may be configured based on a correlation over the set of analysis bins between the computed overall performance metric and the ML performance metric.Type: GrantFiled: April 11, 2022Date of Patent: July 18, 2023Assignee: International Business Machines CorporationInventors: Rafal Bigaj, Lukasz G.

Patent number: 11556860Abstract: An ML root model format having a root model definition, is converted into an ML target model format not having the root model definition. A learning system is assigned to the root model definition that is convertible to the machine learning target model format.
