  • Publication number: 20250094316
    Abstract: For a set in sets of candidate factors, a classification model is trained to predict a computer problem possibility, an accuracy score of the classification model is determined based on model validation, and factor weights of the candidate factors in the set are adjusted based on the accuracy score. This processing is done with respect to all sets of candidate factors. A low accuracy classification model having an accuracy score lower than a threshold criterion is selected. A higher accuracy classification model having an accuracy score that is higher than the accuracy score of the low accuracy classification model is selected. The set of candidate factors used to train the low accuracy classification model is updated using one or more of the candidate factors used to train the higher accuracy classification model. The low accuracy classification model is updated based on the updated set of candidate factors.

  • Patent number: 12248456
    Abstract: A computer-implemented method, system and computer program product for improving accuracy and efficiency of auditing databases. A table, list or index of a database is analyzed to identify metadata, which includes time series data, user data, an Internet Protocol address and operation data. The identified metadata is associated with the corresponding record or row of the table, list or index from which the metadata was extracted. A determination is then made as to whether to record a raw data image associated with the record or row of the analyzed table, list or index based on the corresponding data operation. The identified metadata as well as the recorded data images, if any, are stored in a structured audit log. Auditing information is then obtained from a structured audit log based on matching the record or row identifier (RID) associated with the query with the RID associated with the structured audit log.

    Abstract: A system and method for improving the performance and reducing costs of a program by automatically provisioning and managing proper memory pool cell size adaptive to each executing application. By collecting time series of historical data on the memory pool usage of applications over a period of time, respective time-series prediction models are used to process the data to predict the allocation size for applications and in particular, a predicted number of allocations and a respective predicted allocation cell size. A clustering-based method is further applied to predict the allocation size for applications, using real time execution to do scaling, complement and interpolation. A method runs a further time-series prediction model trained to predict, based on the predicted memory cell size and one or more application profile features associated with the requesting application, a tuning parameter to refine the memory pool storage area size used for handling memory allocation requests.
