Network embedding has proved extremely useful in a variety of network analysis tasks such as node classification, link prediction, and network visualization. Almost all the existing network embedding methods learn to map the node IDs to their corresponding node embeddings. This design principle, however, hinders the ex…

The Nash-Kuiper Theorem states that the collection of C1C^1-isometric embeddings from a Riemannian manifold MnM^n into EN\mathbb{E}^N is C0C^0-dense within the collection of all smooth 1-Lipschitz embeddings provided that n<Nn < N. This result is now known to be a consequence of Gromov's more general hh-principle. Ther…

We propose a principle for exploring context in machine learning models. Starting with a simple assumption that each observation may or may not depend on its context, a conditional probability distribution is decomposed into two parts: context-free and context-sensitive. Then by employing the log-linear word production…

We establish an hh-principle for exact Lagrangian embeddings with concave Legendrian boundary. We prove, in particular, that in the complement of the unit ball BB in the standard symplectic R2n,2n6\R^{2n}, 2n\geq 6, there exists an embedded Lagrangian nn-disc transversely attached to BB along its Legendrian boundary.

On a Weinstein manifold, we define a constructible co/sheaf of categories on the skeleton. The construction works with arbitrary coefficients, and depends only on the homotopy class of a section of the Lagrangian Grassmannian of the stable symplectic normal bundle. The definition is as follows. Take any, possibly high …

We prove prove a bridge principle at infinity for area-minimizing surfaces in the hyperbolic space H3\mathbb{H}^3, and we use it to prove that any open, connected, orientable surface can be properly embedded in H3\mathbb{H}^3 as an area-minimizing surface. Moreover, the embedding can be constructed in such a way that t…

Sequential and temporal data arise in many fields of research, such as quantitative finance, medicine, or computer vision. A novel approach for sequential learning, called the signature method and rooted in rough path theory, is considered. Its basic principle is to represent multidimensional paths by a graded feature …

Network embedding aims to learn the low-dimensional representations of vertexes in a network, while structure and inherent properties of the network is preserved. Existing network embedding works primarily focus on preserving the microscopic structure, such as the first- and second-order proximity of vertexes, while th…

In this paper, we show that any open orientable surface S can be properly embedded in H^3 as a minimizing H-surface for any 0<=H<1. We obtained this result by proving a version of the bridge principle at infinity for H-surfaces. We also show that any open orientable surface S can be nonproperly embedded in H^3 as a min…

In this paper we study the embedding of Riemannian manifolds in low codimension. The well-known result of Nash and Kuiper says that any short embedding in codimension one can be uniformly approximated by C1C^1 isometric embeddings. This statement clearly cannot be true for C2C^2 embeddings in general, due to the classi…

Most existing word embedding approaches do not distinguish the same words in different contexts, therefore ignoring their contextual meanings. As a result, the learned embeddings of these words are usually a mixture of multiple meanings. In this paper, we acknowledge multiple identities of the same word in different co…
