[theano-users] How can I calculate the size of output of convolutional operation in theano?

[Sunjeet Jena]

Is there any way I can calculate the size of the output after the
Convolution Operation?

You should check this out

The output size is in general o = (i - r + 2p)/s + 1 where i is the input
size, o the output size, r the filter size, p the padding and s the stride
of the convolution. This formula holds for every dimension (so for a 2D
convolution, if the strides, padding, filters, etc.. are different you can
apply this formula separately)

You can check theano.tensor.nnet.abstract_conv.get_conv_output_shape()
