1.clone the repositry from https://github.com/yanx27/Pointnet_Pointnet2_pytorch,follow its procedures to download datasets
2.copy our model idknn94.16.py into the folder (/models)
3.function knn_with_dilation in line 431 of idknn94.16.py is our proposed IDKNN, just replace the original KNN with our IDKNN
4.Our model is in line 3249 of idknn94.16.py
5.run train_cls.py to train our model
