Webb20 apr. 2024 · An MLP is just a fully-connected feedforward neural net. In PointNet, a shared MLP means that you are applying the exact same MLP to each point in the point cloud.. Think of a CNN's convolutional layer. There you apply the exact same filter at all locations, and hence the filter weights are shared or tied.If they were not shared, you'd … Webb通过 shared_ptr 的构造函数，可以让 shared_ptr 对象托管一个 new 运算符返回的指针，写法如下：. shared_ptr ptr (new T); // T 可以是 int、char、类等各种类型. 此后，ptr 就可以像 T* 类型的指针一样使用，即 *ptr 就是用 new 动态分配的那个对象。. 多个 shared_ptr 对 …
