CAdam: Context-Adaptive Moment Estimation for 3D Gaussian Densification in Generative Distillation
A novel approach known as Context-Adaptive Moment Estimation (CAdam) tackles the Densification Dilemma encountered in 3D Gaussian Splatting (3DGS) during Generative Distillation. Traditional methods that accumulate based on magnitude fail to distinguish between transient noise and geometric signals, resulting in inefficient representations filled with redundant elements. CAdam reconceptualizes densification as a problem of signal verification rooted in statistics, utilizing the first moment of gradients to apply the interference principle, where stochastic variations are mitigated through destructive interference. This method seeks to achieve a balance between over-densification and under-fitting, enhancing the effectiveness of 3DGS in generative applications. This research is detailed in arXiv paper 2605.20872.
