New Features in 1.4.x
Cluster Similarity: Ability to compare the feature importances of up to three clusters at the same time.
Model Retraining: Improvements to the retraining functionality.
Data Analysis features: Model accuracy, similarity scores, and a variety of graphs (trends plot,
feature plot, correlation plot, cluster evidence, etc.) provide more tools for analysis.
Expanded Operating Modes: Includes additional operating modes for generators (ON/OFF).
SP-4124 Feature Graphs render data outside the defined date/time frame
SP-4197 Event cards from other operating modes are shown in empty assets
SP-4232 The Reset link is not being displayed on the correlation plot when customized dates are selected from the calendar
SP-4250 On the Cluster Similarity view, the matched count is not displaying correctly
SP-4309 Filters are not resetting on the Models page when navigating away from that page
SP-4320 The risk threshold does not stay relative to the risk index when viewing the
risk index and a tag
SP-4321 The UI appears to timeout when an invalid date is entered into the date/time picker
SP-4337 Drop-down values are empty when anomalous events are classified to a cluster
SP-4340 Cluster Similarity drop-down lists are not ordered correctly
SP-4341 Correlation Plot lookback filters are not performing correctly
SP-4357 Previously selected filters of operating modes are displayed when navigating from the Events tab to the Dashboard
SP-4364 All event cards are being displayed after the Apply Filter button is selected when navigating from the Cluster list to the Event tab
SP-4366 Pagination remains set to the selected options even when navigating to another tab
SP-4367 An alert should be deleted when the only user receiving the alert is removed
from the system
SP-4391 Cluster Evidence plots are not loading if there is no interpolated data SP-4397 Search is not working correctly on the Cluster Evidence view
SP-4418 Histograms are not rendering properly
SP-4433 Multiple periods after the @ symbol in an email address was causing an error
in user creation
SP-4444 New data does not get classified correctly after refit when at least 1000 minutes of similar anomalies are labeled
SP-4464 User-generated histograms do not update after retraining
• There is a known issue when you try to refit a small cluster with just one event. The refit operation fails in this case. To avoid this issue, ensure that clusters have at least two events so that SparkPredict can make a hold-out set to calculate accuracy.
• There is a known issue when an operating mode only has 1 or 2 clusters. Due to the small number of clusters, the model cannot provide good histograms and model metadata for those clusters.
