Notes

Research-use weights for reproducing the paper's TTM-B/E/A (512/1024/1536 context). Training data taken from paper Table 8 (Monash subset + LibCity datasets obtained from Salesforce/lotsa_data, ~1B samples). The card itself does not list datasets; the link to Table 8 rests on the 'full reproducibility' statement. Paper: LibCity = 'all datasets released by the Moirai authors ... (except the Rotterdam dataset)'.
