We propose a novel multi-head graph second-order pooling method for graph transformer networks. We normalize the covariance representation with an efficient feature dropout for generality. We fuse the first- and second-order information adaptively. Our proposed model is superior or competitive to state-of-the-arts on six benchmarks. fish sandwich buffalo ny
