+## Introduction
+HSG is a **hyperbolic representation learning framework** that models scene graphs in non-Euclidean space to better capture hierarchical relationships for structured 3D scene understanding. 
+
+HSG data is converted from Apple's [ARKitScenes](https://github.com/apple/ARKitScenes) by transforming its 3D annotations to 2D.
