I have several sequences of univariate real-valued time-series data. The sequences are of different lengths and right now I cannot batch them and feed them to a network. What is the correct procedure to pad these sequences? Is it even possible in this case since I can't use any number as a special symbol?
I'm working with arbitrary univariate time-series data (not related to one specific domain, unbounded range). To give example of one such a series consider standardized stock dataset (only first 10 elements shown):
d = array([-0.37807043, 0.14321786, -0.37807043, 0.13478392, 0.18733381, 1.19576774, 0.25675156, 0.26064414, 0.30930144, 0.38650436])
