Features of the New Type Global Recession [PDF]

open access: yesSHS Web of Conferences, 2021
Research background: The increasing global economic decrease that got the name of Great Lockdown had world pandemic as its trigger. It is already obvious that by its depth, breadth and the number of economics included this recession can be compared to ...

Robust Head Pose Estimation Using Extreme Gradient Boosting Machine on Stacked Autoencoders Neural Network

open access: yesIEEE Access, 2020
Head pose estimation is an important sign in helping robots and other intelligence machines understand human. It plays a vital role in designing human computer interaction systems because many applications rely on precise results of head pose angles such

Decomposing Global Feature Effects Based on Feature Interactions

open access: yes, 2023
Global feature effect methods, such as partial dependence plots, provide an intelligible visualization of the expected marginal feature effect. However, such global feature effect methods can be misleading, as they do not represent local feature effects of single observations well when feature interactions are present. We formally introduce generalized

3D face recognition: A comprehensive survey in 2022

open access: yesComputational Visual Media, 2023
In the past ten years, research on face recognition has shifted to using 3D facial surfaces, as 3D geometric information provides more discriminative features. This comprehensive survey reviews 3D face recognition techniques developed in the past decade,

Traffic sign recognition by combining global and local features based on semi‐supervised classification

open access: yesIET Intelligent Transport Systems, 2020
The legibility of traffic signs has been considered from the beginning of design, and traffic signs are easy to identify for humans. For computer systems, however, identifying traffic signs still poses a challenging problem.

Weakly Supervised Local-Global Attention Network for Facial Expression Recognition

open access: yesIEEE 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 ...

FMNN:Text Classification Model Fused with Multiple Neural Networks [PDF]

open access: yesJisuanji kexue, 2022
Text classification is a basic and important task in natural language processing.Most of the text classification methods based on deep learning only focus on a single model structure.The single structure lacks the ability to simultaneously capture and ...

On Global Types and Multi-Party Session [PDF]

open access: yes, 2011
Global types are formal specifications that describe communication protocols in terms of their global interactions. We present a new, streamlined language of global types equipped with a trace-based semantics and whose features and restrictions are ...

Classification with Global, Local and Shared Features [PDF]

open access: yes, 2012
We present a framework that jointly learns and then uses multiple image windows for improved classification. Apart from using the entire image content as context, class-specific windows are added, as well as windows that target class pairs. The location and extent of the windows are set automatically by handling the window parameters as latent ...
