Analytics Server and Analytics Builder: Model building fails with Confidence Model enabled

Analytics Builder: Max Field limits are ignored during predictive model creation
If the Redundancy Filter is enabled during predictive model creation, features are ranked according to the information gain they provide. The value in Max Fields limits the model to a specific number of fields during training. This Max Fields value is being ignored. This issue has been resolved so that the limits on the number of features included during training are observed.

Anomaly Alert: Returns an inaccurate error message during modification
When modifying an existing anomaly alert on a Thing in ThingWorx Composer, an inaccurate error message displays saying that the selected Analytics Gateway does not exist. A work around was provided earlier to the users as follows: change the Alert Type to something other than Anomaly, make the desired modification, and then switch the Alert Type back to Anomaly.
This issue has been resolved now.

Analytics Builder: Scoring records from a REST request are not displayed correctly
When a predictive scoring job is submitted via a REST API request, the information displayed on the Model list page in Analytics Builder is incorrect. The Number of Records Scored column should reflect the number of data rows submitted in the REST request. Instead, it displays a value of 0.
This issue will be resolved in a future release.

Confidence Model Scoring for Boolean and Categorical Goals
|
|---|
|
In ThingWorx Analytics Server 8.5, confidence models for Boolean and categorical goals could be created during training. When these confidence models are scored, the scoring output includes confidence interval information along with the prediction results. In a future release, the confidence interval information will no longer be returned as part of the scoring results for confidence models created in Analytics Server 8.5 with Boolean or categorical goals. In preparation for future upgrades, you should update any application code that is related to scoring these types of models. Ensure that your application code does not rely on the confidence interval results.
