Multi-modal entity alignment in hyperbolic space

چکیده

Many AI-related tasks involve the interactions of data in multiple modalities. It has been a new trend to merge multi-modal information into knowledge graph (KG), resulting graphs (MMKG). However, MMKGs usually suffer from low coverage and incompleteness. To mitigate this problem, viable approach is integrate complementary other MMKGs. end, although existing entity alignment approaches could be adopted, they operate Euclidean space, representations can lead large distortion KG’s hierarchical structure. Besides, visual yet not well exploited. In response these issues, work, we propose novel approach, Hyperbolic (HMEA), which extends representation hyperboloid manifold. We first adopt Graph Convolutional Networks (HGCNs) learn structural entities. Regarding information, generate image embeddings using densenet model, are also projected hyperbolic space HGCNs. Finally, combine structure use aggregated predict potential results. Extensive experiments ablation studies demonstrate effectiveness our proposed model its components.

Retropharyngeal Space Schwannoma: A Rare Entity

Introduction: Retropharyngeal space schwannomas are rare entities. About 20-45% of schwannomas occur in the head and neck region; however, they represent less than 1% of all head and neck tumors.  Case Report: We present the case of a 36-year-old woman complaining of dysphagia caused by a large schwannoma arising in the posterior pharyngeal wall with remarkable reduction of the oropharyngeal sp...

Feature-Based Alignment of Volumetric Multi-modal Images

This paper proposes a method for aligning image volumes acquired from different imaging modalities (e.g. MR, CT) based on 3D scale-invariant image features. A novel method for encoding invariant feature geometry and appearance is developed, based on the assumption of locally linear intensity relationships, providing a solution to poor repeatability of feature detection in different image modali...

A parallel approach for alignment of multi-modal gridbased data

Multi-modal registration is still a big challenge in image processing. In this article we present a variation of the wellknown fast Fourier transform (fft) accelerated methods for finding the alignment between two datasets, i.e. the rigid transformation consisting of a rotation as well as a translation mapping all regions in both datasets belonging together in an optimal manner. Our method can ...

Inductive Entity Typing Alignment

Aligning named entity taxonomies for comparing or combining di↵erent named entity extraction systems is a di cult task. Often taxonomies are mapped manually onto each other or onto a standardized ontology but at the loss of subtleties between di↵erent class extensions and domain specific uses of the taxonomy. In this paper, we present an approach and experiments for learning customized taxonomy...

Hyperbolic Space

Radial lines, suitably parameterized, are geodesics, but notice that the distance from the origin to the (Euclidean) unit sphere is infinite. This model makes it intuitively clear that the boundary at infinity of hyperbolic space is Sn−1. Hyperbolic space together with its boundary at infinity has the topology of a closed ball, and isometries of hyperbolic space extend uniquely to a homeomorphi...
