Event Arguments Extraction via Dilate Gated Convolutional Neural Network With Enhanced Local Features

IEEE Access, 2020
Event Extraction plays an important role in information-extraction to understand the world. Event extraction could be split into two subtasks: one is event trigger extraction, the other is event arguments extraction.

Salient Local 3D Features for 3D Shape Retrieval

, 2011
In this paper we describe a new formulation for the 3D salient local features based on the voxel grid inspired by the Scale Invariant Feature Transform (SIFT).

Weakly Supervised Local-Global Attention Network for Facial Expression Recognition

IEEE Access, 2020
Combining global and local features is an essential solution to improve discriminative performances in facial expression recognition tasks. The limitations of existing methods are that they cannot extract crucial local features and ignore the ...

Extending local features with contextual information in graph kernels

, 2015
Graph kernels are usually defined in terms of simpler kernels over local substructures of the original graphs. Different kernels consider different types of substructures. However, in some cases they have similar predictive performances, probably because

Local Features with Large Spiky non-Gaussianities during Inflation

, 2012
We provide a dynamical mechanism to generate localized features during inflation. The local feature is due to a sharp waterfall phase transition which is coupled to the inflaton field. The key effect is the contributions of waterfall quantum fluctuations

Unsupervised Texture Segmentation using Active Contours and Local Distributions of Gaussian Markov Random Field Parameters [PDF]

, 2012
In this paper, local distributions of low order Gaussian Markov Random Field (GMRF) model parameters are proposed as texture features for unsupervised texture segmentation.Instead of using model parameters as texture features, we exploit the variations ...

Localized pemphigus with vegetative features

Dermatology Online Journal, 2012
We present a 58-year-old Jamaican man with an eight-month history of an isolated, vegetative, eroded, and crusted plaque on the posterior aspect of the scalp. One month prior to referral to the Charles C. Harris Skin and Cancer Pavilion he developed a few, scattered erosions on the extremities.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

CMB anomalies and the effects of local features of the inflaton potential [PDF]

, 2017
Recent analysis of the WMAP and Planck data have shown the presence of a dip and a bump in the spectrum of primordial perturbations at the scales $k=0.002$ Mpc${}^{-1}$ and $k=0.0035$ Mpc${}^{-1}$ respectively. We analyze for the first time the effects a
