  • Publication number: 20250245635
    Abstract: There are provided systems and methods for scenario-based decisioning by machine learning models for data processing retry success. A service provider, such as an electronic transaction processor for digital transactions, may detect a failure of data processing for a transaction or other request when processed with a data processing system. In order to minimize cost and wasted resources for retrying transactions that are likely to further fail, machine learning models may be implemented that generates a predictive score for whether a failed transaction is likely to be successful if retried with the data processing system. This may be done when the transactions are received or detected, which may occur prior to failures, for different scenario-based decisioning. Scenarios for failures may be processed by the models with different retry strategies and a predictive score may be used to predict a probability of success of the retry.

  • Patent number: 10769115
    Abstract: The concepts relate to data handling, and more specifically to data handling scenarios where data is revised on one computer and stored on another computer. One example can obtain a set of blobs relating to revisions of a file. The example can determine a target size of datastore blobs. In an instance where a total size of the set of blobs is less than the target size, this example can aggregate the set of blobs into an individual datastore blob. Otherwise, the example can identify new or edited individual blobs of the set and aggregate the new or edited individual blobs into first datastore blobs. The example can also aggregate other individual blobs of the set into second datastore blobs.
