Spiking Point Transformer (AAAI 2025)

🚀 This is the official PyTorch implementation of the AAAI 2025 paper:
Spiking Point Transformer for Point Cloud Classification

Data Preparation

Ensure your directory structure follows:

│Spiking_Point_Transformer/
├── config/
├── data/
│   ├── modelnet40_normal_resampled/
│   ├── ScanObjectNN/
├── .......

ModelNet40 Dataset:
Download the aligned ModelNet dataset from here and extract it to data/modelnet40_normal_resampled/.

ScanObjectNN Dataset:
Download the official data from here and extract it into data/ScanObjectNN/.
