[theano-users] theano.scan: ValueError: length not known & Question regarding sequences and previous values

Hi everybody, I am trying to approximate a function that consist of multiple overlapping Gaussian kernels. The calculation should be done in the scan function that iterates over the Gaussian kernels. At this point I got stuck with two problems. 1. I have tried to calculate the sum of all

[theano-users] Scan checkpointing - what exactly theano stores?

So the scan checkpointing seems very ineteresting from the prespective that it can be used for things like learning-to-learn. However, my question is can we tell Theano which part of each N-th iteration it to store and which not? For instance in the learning-to-learn framework where we unroll
