FAQ

Questions arquero owners ask.

  • 01

    Does it drop the original categorical column?

    No. The engine appends new binary columns (e.g., City_London, City_Paris) and preserves the original column so the AI can verify the encoding accuracy.

  • 02

    What if there are hundreds of unique categories?

    The engine processes them all instantly. However, be aware that a massively expanded JSON returned to the LLM may consume significant context tokens. Consider grouping rare categories before encoding.

  • 03

    Can it encode multiple columns at once?

    Currently, the engine accepts one target column per execution for deterministic validation. The AI can chain multiple calls to encode several columns sequentially.
