WebPointHop: An Explainable Machine Learning Method for Point Cloud Classification. minzhang-1/PointHop • • 30 Jul 2024 In the attribute building stage, we address the problem of unordered point cloud data using a space partitioning procedure and developing a robust descriptor that characterizes the relationship between a point and its one-hop neighbor in … WebFeb 9, 2024 · The PointHop method was recently proposed by Zhang et al. for 3D point cloud classification with unsupervised feature extraction. It has an extremely low training complexity while achieving state-of-the-art classification performance. In this work, we improve the PointHop method furthermore in two aspects: 1) reducing its model … WebJul 30, 2024 · An explainable machine learning method called the PointHop method was proposed for point cloud classification in this work. It builds attributes of higher dimensions at each sampled point through iterative one-hop information exchange. This is analogous to a larger receptive field in deeper convolutional layers in CNNs. ppt shockwave flash object
