TetraSphere introduces a novel approach using steerable 3D spherical neurons and vector neurons to create an O(3)-invariant descriptor for point cloud analysis. The method embeds 3D spherical neurons into 4D vector neurons, enabling end-to-end training. By performing TetraTransform, the model extracts deeper O(3)-equivariant features using vector neurons. This integration into the VN-DGCNN framework sets a new performance standard in classifying real-world object scans and synthetic data. The practical value of steerable 3D spherical neurons is demonstrated through improved learning in 3D Euclidean space.
