as linear methods. Recently, we introduced an eigenvector method—called locally linear embedding (LLE)—for the problem of nonlinear dimensionality reduction[4]. This problem is illustrated by the nonlinear manifold in Figure 1. In this example, the dimen-sionality reduction by LLE succeeds in identifying the underlying structure of the

non-linear embedding that is necessary for more complex data. Spectral clustering and its variants have gained popular-ity recently (Von Luxburg,2007). They allow more flex-ible distance metrics and generally perform better than k-means. Combining spectral clustering and embedding has been explored inYang et al.(2010);Nie et al.(2011).Tian

Structural Deep Network Embedding method, namely SDNE. More specifically, we first propose a semi-supervised deep model, which has multiple layers of non-linear functions, thereby being able to capture the highly non-linear network structure. Then we propose to exploit the first-order and second-order proximity jointly to p-

In contrast to these approaches, FaceNet directly trains its output to be a compact 128-D embedding using a triplet-based loss function based on LMNN [19]. Our triplets con-sist of two matching face thumbnails and a non-matching

Knowledge Graph Embedding: A Survey of Approaches and Applications Quan Wang, Zhendong Mao, Bin Wang, and Li Guo Abstract—Knowledge graph (KG) embedding is to embed components of a KG including entities and relations into continuous vector spaces, so as to simplify the manipulation while preserving the inherent structure of the KG.

If, for example, the embedding Wm;p(Rn) ‰ Lq(Rn) is known to hold, similar property will be true for the spaces over Ω. We will quote below a theorem justifying existence of such extension operator: Theorem 1. Let Ω be either a half-space in Rn …
