ZEPI-Net: Light Field Super Resolution via Internal Cross-Scale Epipolar Plane Image Zero-Shot Learning
Springer Science and Business Media LLC - Tập 55 - Trang 1649-1662 - 2022
Many applications of light field (LF) imaging have been limited by the spatial-angular resolution problem, hence the need for efficient super-resolution techniques. Recently, learning-based solutions have achieved remarkably better performances than traditional super-resolution (SR) techniques. Unfortunately, the learning or training process relies heavily on the training dataset, which could be l...... hiện toàn bộ
Using Laplacian Eigenmap as Heuristic Information to Solve Nonlinear Constraints Defined on a Graph and Its Application in Distributed Range-Free Localization of Wireless Sensor Networks
Springer Science and Business Media LLC - Tập 37 - Trang 411-424 - 2012
In this paper, we are concerned with the problem of nonlinear inequalities defined on a graph. The feasible solution set to this problem is often infinity and Laplacian eigenmap is used as heuristic information to gain better performance in the solution. A continuous-time projected neural network, and the corresponding discrete-time projected neural network are both given to tackle this problem it...... hiện toàn bộ
Systematic Homonym Detection and Replacement Based on Contextual Word Embedding
Springer Science and Business Media LLC - Tập 53 - Trang 17-36 - 2020
Homonyms are words that share their spelling but differ in meaning and are a common feature in most languages. Homonyms are a source of noise i most text analyses and are difficult to detect; numerous studies have been conducted in this regard. However, extant methods typically detect homonyms using a rule-based or statistical-based approach, which requires an answer set, with little regard to the...... hiện toàn bộ
Dirichlet Graph Convolution Coupled Neural Differential Equation for Spatio-temporal Time Series Prediction
Springer Science and Business Media LLC - Tập 55 - Trang 12347-12366 - 2023
In recent years, multivariate time series prediction has attracted extensive research interests. However, the dynamic changes of the spatial topology and the temporal evolution of multivariate variables bring great challenges to the spatio-temporal time series prediction. In this paper, a novel Dirichlet graph convolution module is introduced to automatically learn the spatio-temporal representati...... hiện toàn bộ
On the Weighted Pseudo-Almost Periodic Solution for BAM Networks with Delays
Springer Science and Business Media LLC - Tập 48 - Trang 849-862 - 2017
In this paper, a class of Bidirectional Associative Memory neural networks with time-varying weights and continuously distributed delays is discussed. Sufficient conditions are obtained for the existence and uniqueness of weighted pseudo-almost periodic solution of the considered model and numerical examples are given to show the effectiveness of the obtained results.

$${\varvec{p}}$$ th Moment Exponential Stability of Hybrid Delayed Reaction–Diffusion Cohen–Grossberg Neural Networks
Springer Science and Business Media LLC - Tập 46 - Trang 83-111 - 2016
In this paper, we propose hybrid reaction–diffusion Cohen–Grossberg neural networks (RDCGNNs) with variable coefficients and mixed time delays. By using the Lyapunov–Krasovkii functional approach, stochastic analysis technique and Hardy inequality, some novel sufficient conditions are derived to ensure the pth moment exponential stability of hybrid RDCGNNs with mixed time delays. The obtained suff...... hiện toàn bộ
A Weakly Connected Memristive Neural Network for Associative Memory
Springer Science and Business Media LLC - Tập 40 Số 3 - Trang 275-288 - 2014
A New Attention-Based LSTM for Image Captioning
Springer Science and Business Media LLC - Tập 54 - Trang 3157-3171 - 2022
Image captioning aims to describe the content of an image with a complete and natural sentence. Recently, the image captioning methods with encoder-decoder architecture has made great progress, in which LSTM became a dominant decoder to generate word sequence. However, in the decoder stage, the input vector keep same and there is much uncorrelated with previously visual parts or generated words. I...... hiện toàn bộ
Multi-weighted Complex Structure on Fractional Order Coupled Neural Networks with Linear Coupling Delay: A Robust Synchronization Problem
Springer Science and Business Media LLC - Tập 51 - Trang 2453-2479 - 2020
This sequel is concerned with the analysis of robust synchronization for a multi-weighted complex structure on fractional-order coupled neural networks (MWCFCNNs) with linear coupling delays via state feedback controller. Firstly, by means of fractional order comparison principle, suitable Lyapunov method, Kronecker product technique, some famous inequality techniques about fractional order calcul...... hiện toàn bộ
