Release Overview
Enhancements
OpenTelemetry Redesign. Changed how we are passing through telemetry information in each solution.
New Consumption Group Model Hyperparameters can be configured and used to return hyperparameters for every model used when running a prediction.
Monitor System - Improved descriptions and documentation in the solution outlining usage guidelines for users. Inclusion of one default rule automatically included on all projects. Cleanup to table ports correctly add all required columns, enabling existing projects to leverage the system
Xperiflow Administration Tools (XAT) - New system default RSI role, the Operator has the ability to run jobs and routines. This role is similar to the Admin role, but without delete permissions.
Bug Fixes
- Forecast Agent - now able to download or copy a table when fully expanded
- Data Refresh can now process multiple datasources without database integrity errors
Dependencies
XPFv4.4.0
XBR-SV240-XPFv4.4.0-PV930
Known Issues
- Filling out multiple drop-down boxes within Source Data Upload, Feature Data Upload, or Data Update dialog input forms too quickly will fill in with defaulted dimension values instead of persisting the previously selected values. Recommendation: do not click through as fast as possible.
- Within the Pipeline Arena page or the Analysis Forecast page, when navigating from the Waterfall or Periodic Explanations views to the Tug Of War view will result in the Tug Of War plot only taking up half the screen. Recommendation: click a dropdown from the model arena table to fix the width of the tug of war visual.
- In the windows application, within the Pipeline Arena page, Analysis Forecast page, Artifacts page on theRuns page of STU*,* within the Forecast Agent, or when inputting parameters for Routine Runs within STU, users may see tooltips over buttons that do not make sense.
- Within the Pipeline Arena or the Analysis Forecast page, the PolyElasticNet and Cubist Model variants will generate Feature Impact results but will not generate Feature v. Actual plot data.
- The solution does not block you from making project model build alterations while that project is being copied. Recommendation: it is advised that you avoid making alterations to the project while it is being copied.
- When running model builds that leverage Hierarchical Forecasting with reconciliation, it is possible for targets disregards the Allow Negative Targets setting No and actually product forecasts with negative target values.
- When projects are running pipelines or other costly jobs consuming more than 75% of server resources, page rendering speeds may increase by 25%.
- On a project restart, previously configured events may be removed. Recommendation: revisit events and assignments after restarting a project.
- Users are not blocked from running the restart job while a project copy is running. This is not recommended as the projects may end up being in different states. Recommendation: do not run a restart job (or any other job) while a project is being copied.
- Direct export of SensibleAI Forecast DMF tables that utilize hierarchical forecasting will require manual intervention to populate unused dimension columns with real values.
- When viewing large paginated tables of the error log within the Forecast Agent, the “next page” button may not be visible or usable. Please use the AI Activity Center to parse through more records as needed.
- Backtest functionality has not been functional for several releases now, cannot enable backtest in a split configuration. Can be mitigated with manual backtests (i.e. cut training data off one forecast range early → predict and compare to actuals).
- When running Retro explanations as a batch job, selections besides “All Models (All Targets)” can cause issues resulting in webservices being locked up.
- A change was introduced to data update that increases the run time significantly. This change was required to allow retro explanations to be on demand.
- FOR projects created before XPF 4.3.0 will not be able to initially leverage the monitor system. Enablement of the monitor system for pre 4.3.0 projects will require the submission of a Xperiflow support ticket.
- In Forecast Agent, if you send a chat while the agent is in flight the message will disappear. The agent should continue fine, you will just to retype your follow-up
