I don’t think that I quite understand your solution. let’s take a simple example, 2 nodes with 2 features each, 2 time stamps and a kernel of size 1x2 filled with ones. As you can see from the image the two timestamps are convolved into one, but there is no information going from node 1 to node 2 which is intended. Now I would like for each node to have it’s own filter, so features 1,2 are going to be multiplied with a filter and 2,4 with another, and same thing for the other channel.
Thank in advance for the response, and I really appreciate your help.
