FAQ

Questions Native V8 owners ask.

  • 01

    What is the difference between RMSE and MAE?

    RMSE heavily penalizes large errors (because the errors are squared before averaging), while MAE treats all errors equally linearly.

  • 02

    Can it handle negative predictions?

    Yes, the exact mathematical formulas handle all floating-point numbers including negatives.

  • 03

    Is this done local?

    Yes. All validation metrics are computed locally on the Vinkius Edge Runtime with zero external API calls, ensuring high privacy.
