Distribution Guidance Network for Weakly Supervised Point Cloud Semantic Segmentation

Neural Information Processing Systems

Our initial investigation identifies which distributions accurately characterize the feature space, subsequently leveraging this priori to guide the alignment of the weakly supervised embeddings. Specifically, we analyze the superiority of the mixture of von Mises-Fisher distributions (moVMF) among several common distribution candidates.

We then apply the framework to the challenging practical setting where confounding factors (that induce spurious correlations) are observable only on asmall fraction of data.
