Researchers have developed a new quantization technique called Fisher-Guided Quantization (FGQ) to reduce the memory and computation overhead of Visual Geometry Transformer (VGGT) models. These models, used for 3D reconstruction tasks like depth estimation and camera pose prediction, are challenging to deploy on devices due to their large parameter count. 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.
