Hello,
Im quite new in theano.
My problem translated in numpy is :
I have two matrices of unknown shape:
x =
[[ 1., 2., 3., 4.],
[ 5., 6., 7., 8.],
[ 9., 10., 11., 12.],
[ 1., 2., 3., 4.],
[ 5., 6., 7., 8.],
[ 9., 10., 11., 12.],
[ 19., 27., 33., 24.],
[ 54., 66., 74., 38.],
[ 29., 210., 131., 412.],
[ 13., 21., 33., 41.],
[ 55., 66., 74., 83.],
[ 92., 106., 711., 142.]]
and y = [0, 10, 82, 10, 82, 0, 2, 2, 9, 2, 0, 10] #vector of id
I want to create a list of matrix regrouping rows of same index such as :
result =
[[ 1., 2., 3., 4.], [ 9., 10., 11., 12.],[ 55., 66., 74.,
83.]] #rows from X with index 0
[[ 5., 6., 7., 8.], [ 1., 2., 3., 4.], [ 92., 106.,
711., 142.]] #rows from X with index 10
[[ 9., 10., 11., 12.], [ 5., 6., 7., 8.]]
#rows from X with index 82
[[ 19., 27., 33., 24.],[ 54., 66., 74., 38.]],[ 13., 21.,
33., 41.]] #rows from X with index 2
[[ 29., 210., 131., 412.]]
#rows from X with index 9
Thanks
