FactoryTalk Analytics DataFlowML Processors for ThingWorx Analytics
|
|
This release provides an integration between DataFlowML and ThingWorx Analytics. The integration includes four custom processors that can be built into DataFlowML pipelines. When implemented, these custom processors provide DataFlowML users with API access to ThingWorx Analytics machine learning functionality. The custom processors available for use include the following:
• CreateDatasetProcessor – Creates analytics-ready datasets using ThingWorx Analytics REST APIs and returns a Result ID to your pipeline.
• AsyncPredictionProcessor – Runs asynchronous scoring against a ThingWorx Analytics dataset and returns a Result ID to your pipeline.
• SyncPredictionProcessor – Runs synchronous scoring against a ThingWorx Analytics dataset and returns prediction results to your pipeline.
• ResultProcessor – With a Result ID from an asynchronous scoring job, returns CSV prediction results to your pipeline.

ThingWorx Analytics Server: Two-at-a-time Signals request does not return MI for all field combinations
When running a request for Signals, and specifying maxAtATime = 2, Mutual Information (MI), in relation to the goal, is not returned for all field combinations as expected. Instead, individual (one-at-a-time) MI scores are returned for all fields and then are filtered down to the top 25% most relevant fields. Two-at-a-time signals are calculated only for those fields. There is currently no way to modify this filtering behavior.

ThingWorx Analytics Server: The reported version number is an internal versioning number
The Version Info service currently returns a version number that indicates both the external version and the internal build version, but not a path release version. Possible changes in version information are under consideration for a future enhancement.

Analytics Builder: Filtering on list pages does not work as expected
When filtering is applied to a list page with multiple pages (such as the Models list page), the filtered results are not aggregated for display on a single page. Instead, the filtered results remain on their original pages and multiple pages must be clicked through to find all the filtered results.
To improve handling of list page displays, a configurable parameter has been added to set the number of table items that can be displayed per page. A more permanent resolution for the filtering with pagination issue will be provided in a future release.

Analytics Builder: Screens do not load properly in IE 11
The View Datasets and View Models screens do not load properly in the IE 11 browser for the support Windows operating systems. This issue will be resolved in a future release. To avoid the issue, use another browser, such as Chrome, Firefox, or Safari.

Analytics Builder and Analytics Manager: Sizing of pop-up windows is distorted
When the Analytics Extension is deployed on the 8.3.1 version of ThingWorx platform, the display of some pop-up windows might look compressed in Analytics Builder and Analytics Manager. In some cases, scroll bars will allow you to view truncated fields. However, the best work around for the issue is to maximize your browser view so that the pop-up windows can display fully. This issue will be resolved in a future release.
