SteinDreamer
Streamline text-to-3D synthesis with SteinDreamer, a cutting-edge approach developed by Meta and UT Austin, harnessing the power of Stein’s Identity for variance reduction. Their research addresses the high variance in gradient estimation, a common bottleneck in score distillation methods. Using Stein Score Distillation (SSD), the team leverages control variates to optimize for lower variance, thereby enhancing the visual quality of 3D assets generated from textual descriptions. SteinDreamer offers a versatile platform, incorporating arbitrary baseline functions and network architectures, and outperforms existing methods with faster convergence and more stable gradients....
