🛠️ Technical Deep Dive
- Architecture: Employs a hybrid Transformer-State Space Model (SSM) backbone to handle long-sequence spatial dependencies efficiently.
- Input Processing: Uses a voxel-based tokenization strategy that converts 3D point clouds into spatial embeddings before fusion with text tokens.
- Learning Mechanism: Implements a dual-memory system consisting of a short-term buffer for immediate spatial awareness and a long-term episodic memory for environment mapping.
- Optimization: Utilizes a custom loss function, 'Spatial-Consistency Loss,' which penalizes the model for generating physically impossible spatial configurations.
