Point-Wise Approach for Yandex Personalized Web Search Challenge The paper focuses on feature engineering for learning to rank in web search, including a novel pair-wise feature, shortand long-term personal navigation features. The paper demonstrates that point-wise logistic regression can achieve the...
根据它的设计,PointNet所捕获的局部特征是point-wise的,而不能捕获由度量引起的局部结构。PointNet++先利用Sampling layer和Grouping layer构建局部邻域,再利用PointNet layer编码(提取)局部特征。也就是文章中提到的Hierarchical Point Set Feature Learning。 PointNet的采样密度是uniform的,而PointNet++可以处理non-uniform ...

通过3D和2D之间的映射关系,提取2D图像上对应点的point feature,即3D point → 2D point → point features。 To fetch the corresponding point-wise image features, we project LiDAR points onto the image plane by a homogeneous transformation to set up the correspondence. Afterwards, LiDAR points are ...

做法:cat[local 2d feature, 3d feature] 外接J个head,每个Head独立预测自己的joint embedding特征,该joint wise feature将作为condition信息,在diffusion每个迭代轮次均被使用。 算法pipeline看图即可,与diffusion model几乎一致了。 Code Code Link 分析一下xx.py,Q1:模型Backbone是什么?Q2:模型预测noise还是预测去噪之...
This is the official implementation of our paper SiT-MLP: A Simple MLP with Point-wise Topology Feature Learning for Skeleton-based Action Recognition Note: Our approch is MLP-based and GCN-free. The graph folder is adopted for different modality. Abstract Graph convolution networks (GCNs) have...
分类heatmap是一个值都在0到1之间的类别C个channels的map,可以想象就是个千层饼,每一层表示对该类在这个map上的分布预测情况。target制作根据实际gt中心位置,用gaussian distribution的密度函数来画,方差也就是半径大小根据实际这个object box的尺寸而定。计算loss使用pixel-wise的focal loss,也就是说每个channel层...
