  • Publication number: 20250258832
    Abstract: An approach to time-series data point anomaly detection is presented. Data point anomalies in time-series data can cause a cascade of incorrect predictions in a time-series data prediction model. Presented herein is an approach to decompose a time-series training data set into elementary components, such as seasonal, trend and residual. The approach determines one or more confidence intervals for elementary components of data points including level shift, variance, and outlier. From these confidence intervals, new data points are analyzed and identified as anomaly data points. The approach also prevents anomaly data points from being incorporated into a time series data prediction model, reducing prediction error in the prediction model.

  • Publication number: 20250252102
    Abstract: Computer implemented methods, systems, and computer program products include program code executing on a processor(s) identifies a query with low performance. The program code generates a small data environment for use in optimizing the query. The program code identifies table(s) and field(s) related to the query with low performance. The program code samples a portion of each table of the one or more tables based on, for each table, parameters of the one or more fields in each table, where the portion sampled comprises records from each table with common data traits to a whole of each table. The program code generates a small data environment comprising the portion of each table. The program code performance tests an optimized version of the query by executing it on the small data environment.

  • Patent number: 12314290
    Abstract: A computer-implemented method for treating post-modeling data includes computing, sequentially for each category of a feature, a category importance (CI) value. The CI value is based on a model accuracy change when records of a category being examined are reassigned to a remaining set of categories of the feature according to a cumulative distribution of records among the remaining set of categories of the feature, wherein the remaining set of categories include all categories of the feature, except for the category being examined. A post-modeling category is performed to merge of each category having the CI value less than a CI value threshold.
