GridPE: A Grid Cell-Inspired Unified Position Embedding for Arbitrary-Dimensional Spaces
Researchers have introduced GridPE, a novel positional embedding framework inspired by the spatial cognition of grid cells in mammals. This method aims to improve the understanding of spatial relationships across arbitrary dimensions, addressing limitations in existing techniques like RoPE for high-dimensional tasks. GridPE integrates principles from computational neuroscience and harmonic analysis, theoretically proving its ability to approximate spatial functions and demonstrating superior performance on tasks such as 2D image classification and 3D point cloud recognition.
