So let’s say I have sequences of different length, I need to zero-pad them all to the same length to work in batches. So for each sequence I “remember” its length. Let’s say for example I have a sequence tensor of 300 x 100, and I “remember” that its actual length is 230, meaning there are 70 zero padded time frames. Now, after I pass that through conv+pool this shrinks to a new size, the old length of 230 is not longer relevant. Did I manage to explain myself? I feel like maybe this is a bit tricky, or I’m missing something.
