This repository contains model weights for LitePT: Lighter Yet Stronger Point Transformer, a lightweight, high-performance 3D point cloud architecture. LitePT proposes an improved 3D point cloud backbone that employs convolutions in early stages and switches to attention for deeper layers, introducing a novel, training-free 3D positional encoding, PointROPE. The resulting model achieves state-of-the-art performance while being significantly more efficient.
