Four Limitations Computationally inefficient to update the hidden states of nodes iteratively to get the fixed point. uses the same parameters in the iteration while most opoular neural networks use different parameters in different layers, which serves as a hierarchical feature extraction method some informative edges(Knowledge Graph) cannot be effectively modeled in GNN. if T is pretty large, ..

$$h_v = f(x_v, x_{co[v]}, h_{ne[v]}, x_{ne[v]}) $$ $$o_v = g(h_v, x_v)$$ Functions $f$: local transition function which is shared among all nodes $g$ : local output function Symbols x: the input feature h: hidden state $co[v]$: the set of edges connected to node $v$ $ne[v]$: the set of neighbors of node $v$ $x_v$: the features of $v$ $x_{co[v]}$: the features of its edges $h_{ne[v]}$: the states..
