New FGQ method slashes Visual Geometry Transformer model size

Researchers have developed a new post-training quantization method called Fisher-Guided Quantization (FGQ) to reduce the memory and computation overhead of Visual Geometry Grounded Transformers (VGGT). These models, used for 3D vision tasks like depth estimation and camera pose prediction, have billions of parameters that hinder on-device deployment. FGQ addresses the issue that different parts of the model have varying sensitivities to quantization errors across different tasks, by using the Fisher information matrix to guide the quantization process and preserve critical components.
