The idea I want to capture is that these different sequences occur at different points in a lifetime. So for an example if I have data that represents info on a given person through the span of their lifetime, but one sequence starts at age 50 while another starts at age 35, I’d like to be able to capture these different ‘start times’  by varying their position within a fixed length sequence.
I suspected as much with pack_padded_sequence / pad_packed_sequence but any other ideas for how to represent these different start times are also much appreciated.
