August may be winding down, but we're definitely not. Kraken now lets you select the algorithms you want to use when training and refining models, Analysis correlations cards are grouped together for easier access, and you can add time-based variables to your prediction datasets with dynamic prediction dataset naming.
Algorithm selection in Analysis Pipeline
When creating or refining an Analysis, after you have selected your target you can expand the "Algorithms" section of the Pipeline to see a list of the algorithms that Kraken will use when training. You can now choose to deselect one or more algorithms that you don't want Kraken to include in the training, which will reduce the amount of time it takes to get your Analysis results. While we recommend that you leave everything enabled the first time you analyze to get a sense of how various algorithms perform, this feature is very handy for subsequent Analysis versions where you have decided on an algorithm and want to quickly refine other aspects of your model, such as feature exclusion or data manipulation with Pipeline steps.
New Correlations card group
When viewing Analysis results for models that support Correlations and/or Target Correlations charts, you'll find them grouped together into a single card group on the Project overview page for easier access. You can click on the thumbnail to access the charts in full screen view, as well as toggle between the thumbnail views when both cards are available for your Analysis.
Dynamic prediction dataset naming
When you create a prediction dataset and enable prediction sync, you can specify the name you'd like for the predicted dataset and include a variety of time-based variables that Kraken will replace with actual values when your prediction dataset is synced. Depending on the variables that you use, this capability allows you to keep a running history of your predictions in your data provider and prevent Kraken from overwriting your prediction dataset every time it is synced to your data provider.

We've also implemented several bug fixes, minor experience enhancements and performance improvements. Some noteworthy items in this release include:
- When clicking REFINE on an existing Analysis, Kraken automatically opens the Pipeline window for faster editing.
- We've improved the dynamic scaling on the SHAP Importance charts for Analyses and Predictions, so that the scale is automatically calculated to the nearest factor of 10 based on your data values for easier interpretation.
- We've added helpful hover text to more icons, including the Dataset Options gear icon and the "+" button to add a Pipeline step.
- The Pipeline includes helpful information when converting a string column.
- Kraken prevents you from inadvertently analyzing a dataset when no features are selected, which previously resulted in an error.
- While previewing MySQL data in table view when creating or refining an Analysis, column headers are no longer potentially misaligned with the column data due to alphabetization.
- We continue to improve the details in error messages created by a data provider to provide more details instead of a generic "ERROR" message.
Reminder: If Kraken is misbehaving, check KIKI first.
All Kraken users have access to KIKI, a.k.a. "Kraken Important Known Issues". If you're experiencing an issue with Kraken, KIKI is your first stop to determine if we're aware of the issue. Where possible, we provide suggested workarounds while we work to eliminate issues. KIKI will be updated as we eliminate issues through Kraken product updates, as well as when new issues are identified.
Reminder: SONAR© Guide content is just a click away!
As a Kraken user, you have access to SONAR© Guide, the proven training methodology from Big Squid and your key to learning everything you need to know to use Kraken effectively and become a citizen data scientist hero in the process. A link to the SONAR© Guide content library is accessible whenever you access Kraken help screens; just look for the SONAR© Guide logo on the right-hand side. It's also available in the SONAR© Guide on the Big Squid Support site.
