Big news! We've added Automatic Threshold Tuning for binary classification models, we've given you a new method to access your scheduled Kraken predictions, and Model Metrics now provides a view into the hyperparameter values used in your models.

Updates in this release

Automatic Threshold Tuning is enabled for all new binary classification models, to provide even more reliable "real world" performance. You can also retrain existing models to apply Automatic Threshold Tuning. Click here to learn more about how it works and what it means for your binary models.
Automated Prediction Download allows you to retrieve your scheduled predictions from Kraken via a URL and API key for all data providers, giving you the ability to access your predictions from virtually any application that supports HTTPS. Click here to learn more about the benefits of this powerful new way to get your Kraken predictions.
To provide more insight into Kraken's model training process, the Model Metrics details for binary, multiclass and regression models now include a display of the hyperparameter values used in the analysis. (Previously this was limited to models trained with Automatic Hyperparameter Optimization.)

• We've also implemented various minor bug fixes as well as performance and interface improvements, including:
  • Kraken no longer erroneously displays duplicate CSV files when viewing the list of datasets.
  • We've improved the indication of where to click to drill to Model Metrics details for models trained with Automatic Hyperparameter Optimization.
  • When selecting an apply dataset, Kraken now clearly indicates it must have the same columns and data types (schema) as the training dataset BEFORE any Data Pipeline steps are applied.
  • Kraken now warns that you will lose your work if you choose to navigate away from the analysis creation screen.

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 section of support.bigsquid.com.

Reminder: If Kraken is misbehaving, check KIKI first.

Registered 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.
