DeepSphere: a graph-based spherical CNN Sep 25, 2019 Blind Submission readers: everyone Show Bibtex TL;DR: A graph-based spherical CNN that strikes an interesting balance of trade-offs for a wide variety of applications. Abstract: Designing a convolution for a spherical neural network requires a delicate tradeoff between efficiency and rotation equivariance. DeepSphere, a method based on a graph representation of the discretized sphere, strikes a controllable balance between these two de

@hillbig DeepSphereは回転操作に対し同変な球面CNNとして、サンプルされた点の頂点とその点間の枝の重みを指数カーネルで定めたグラフ上でラプラシアンLを定義し、Lを使ったグラフ畳み込み操作を行う。従来手法(Spherical CNN)より計算/メモリコストが数分の1であり精度も高い。
