incomplete formula for correlation layer? #14374

Open hubutui opened 5 years ago

Hi, I check https://mxnet.incubator.apache.org/versions/master/api/python/ndarray/ndarray.html#mxnet.ndarray.Correlation, and it seems that the formula of correlation is incomplete. According to FlowNet, it should be:

c(x_{1}, x_{2}) = \sum_{o \in [-k,k] \times [-k,k]} <f_1(x_1+o), f_2(x_2+o)>

Also, adding FlowNet referrence to document may helps.
