摘要:

流形学习在非线性降维领域中占有重要地位,其思想也为其他相关方法提供了借鉴。基于图的方法,如图卷积网络(GCN),显示了与流形学习相同的思想,尽管它们属于不同的领域。受GCN的启发,我们将邻居传播引入到LLE中,提出了局部邻居传播嵌入(LNPE)。与LLE相比,LNPE的计算复杂性线性增加,通过将$1$ -跳邻居扩展为$n$ -跳邻居,增强了邻居之间的局部连接和交互.实验结果表明,LNPE算法具有更好的拓扑和几何特性,嵌入结果更可靠、鲁棒。

英文摘要:

Manifold Learning occupies a vital role in the field of nonlinear dimensionality reduction and its ideas also serve for other relevant methods. Graph-based methods such as Graph Convolutional Networks (GCN) show ideas in common with manifold learning, although they belong to different fields. Inspired by GCN, we introduce neighbor propagation into LLE and propose Local Neighbor Propagation Embedding (LNPE). With linear computational complexity increase compared with LLE, LNPE enhances the local connections and interactions between neighborhoods by extending $1$-hop neighbors into $n$-hop neighbors. The experimental results show that LNPE could obtain more faithful and robust embeddings with better topological and geometrical properties.
