What are the data requirements for fine-tuning?

You generally need at least 100 observations per series, and data must be formatted with the Nixtla schema (unique_id, ds, y). This skill provides scripts to help prepare your data.

What is Nixtla TimeGPT?

Nixtla TimeGPT is a generative pre-trained transformer model specifically designed for time-series forecasting across diverse industries and frequencies.

How do I know if my fine-tuned model is better?

The skill includes a comparison feature that calculates error metrics like SMAPE for both the zero-shot and fine-tuned models on a held-out test set.

Why should I fine-tune a TimeGPT model?

While TimeGPT offers strong zero-shot performance, fine-tuning allows the model to adapt to the specific patterns, seasonalities, and noise present in your unique proprietary data.

Does this skill require a Nixtla API key?

Yes, you must have a NIXTLA_API_KEY set in your environment variables to submit training jobs and receive model IDs from the Nixtla API.
