Hi everyone, just wanted to ask if autoNhits can handle time series of different lengths when fitting. For example when forecasting product sales, new products may be introduced at different times.

Hi @Rachel Yee. Yes, all methods can receive time series from different length. Within a training batch, shorter time series are padded with 0s at the beginning, to match the length of the longest time series.
