Interesting architecture, EGC, it follows the work of PNAs that combines different aggregators and here w is learned while using adaptive filters.
I am delighted to announce our new work "Adaptive Filters and Aggregator Fusion for Efficient Graph Convolutions" w/ @FelixOpo @pl219_cambridge @niclane7
We provide code + pretrained models; find our blog post here: mlsys.cst.cam.ac.uk/research/egc/
