MBGRLp : Multiscale Bootstrap Graph Representation Learning on Pointcloud (Student Abstract)

Point cloud has gained a lot of attention with the availability of large amount of point cloud data and increasing applications like city planning and self-driving cars. However, current methods, often rely on labeled information and costly processing, such as converting point cloud to voxel. We propose a self-supervised learning approach to tackle these problems, combating labelling and additional memory cost issues. Our proposed method achieves results comparable to supervised and unsupervised baselines on widely used benchmark datasets for self-supervised point cloud classification like ShapeNet, ModelNet10/40.
