Does TimeGPT clean/preprocess the data set? #215

Closed gsamaras closed 1 month ago

gsamaras commented 5 months ago

When calling TimeGPT to forecast I see this message:

INFO:nixtlats.timegpt:Preprocessing dataframes...

Does it mean that TimeGPT cleans the data automatically?

Hi @gsamaras! Here, preprocessing indicates formatting the DataFrame to ensure compatibility with TimeGPT's processing requirements. Currently TimeGPT uses a fix scaler when forecasting, so users do not need to scale the data.

@Yibei990826 @gsamaras I think this issue can be closed (?)
