Each of the 50,000 records contains an integer id, raw float32 forcing field a=f with shape [128, 128], raw float32 solution field u=phi with shape [128, 128], and scalar generation parameters alpha and tau. Runtime loaders concatenate a and u into channel-first [2, 128, 128] tensors and apply normalization from metadata.json.", | |
