Neural Pruning for 3D Scene Reconstruction: Efficient NeRF Acceleration
This work addresses efficiency issues for users of NeRF models in resource-limited settings, but it is incremental as it applies known pruning techniques to a specific domain.
The paper tackled the problem of lengthy training times in Neural Radiance Fields (NeRF) for 3D scene reconstruction by applying neural pruning, achieving a 50% reduction in model size and a 35% speedup in training with only a slight accuracy decrease.
Neural Radiance Fields (NeRF) have become a popular 3D reconstruction approach in recent years. While they produce high-quality results, they also demand lengthy training times, often spanning days. This paper studies neural pruning as a strategy to address these concerns. We compare pruning approaches, including uniform sampling, importance-based methods, and coreset-based techniques, to reduce the model size and speed up training. Our findings show that coreset-driven pruning can achieve a 50% reduction in model size and a 35% speedup in training, with only a slight decrease in accuracy. These results suggest that pruning can be an effective method for improving the efficiency of NeRF models in resource-limited settings.
