WebOften a for-loop or while-loop can be expressed as a scan () operation, and scan is the closest that theano comes to looping. The advantages of using scan over for loops in python (amongs other) are: it allows the number of iterations to be part of the symbolic graph. it allows computing gradients through the for loop.
