transformation matrix in the feature space has much higher dimension than the spatial transform matrix, which greatly increases the difficulty of optimization. 对于特征空间的alignment network,由于特征空间维度比较高,因此直接生成的alignment matrix会维度特别大,不好优化,因此这里需要加个loss约束一下。 add a ...

PointNet++: Deep Hierarchical Feature Learning on Point Sets in a Metric Space | Papers With Code 摘要 在先前的研究中很少有人关注点集的深度学习,而PointNet[^20]就是这个方向的先驱。然而,PointNet的设计无法捕捉由点所在的测度空间产生的局部结构,从而限制其识别细粒度模式和对复杂场景的泛化能力。在本次工...
