What is the meaning of preserving local or global structure of …
2022年3月22日 · It embeds data in a lower dimensional space in which light blue is more close to dark blue rather than yellow region, that means local structure was safely preserved, while the global structure of the shape is reduced from a S shape to a simple band (see it as opening or flattening S-shape).
Local and global structure preserving based feature selection
2012年7月15日 · In this paper, we propose two unsupervised FS methods called Local and Global Structure Preserving based Feature Selection (LGFS) and Extended LGFS (E-LGFS), respectively. LGFS firstly constructs a nearest neighborhood graph and a farthest neighborhood graph to describe the local and global structure of samples.

【论文笔记】Self-supervised Graph-level Representation Learning with Local ...
本文研究了无监督/自监督的全图表示学习，提出了一个局部实例和全局语义学习框架（GraphLoG）。 具体来说，除了保留局部相似性，GraphLoG还引入了层次模型来捕捉全局语义集群。 进一步开发了一种高效的在线期望最大化（EM）算法来学习该模型。 模型在大量未标记的图上进行预训练，然后在下游任务上进行微调，最终在化学和生物基准数据集上进行的大量实验证明了所提出的方法的有效性。 全图的表示学习作为一. 写在前面这篇paper是21年发表在ICML …
Efficient Multi-View Graph Clustering with Local and Global Structure ...
2023年10月27日 · To tackle the issue, we propose a novel anchor-based multi-view graph clustering framework termed Efficient Multi-View Graph Clustering with Local and Global Structure Preservation (EMVGC-LG). Specifically, a unified framework with a theoretical guarantee is designed to capture local and global information.
In this paper, we propose to jointly leverage the global KG structure and entity-specific relational triples for better entity alignment. Specifically, a global structure and local semantics preserving network is proposed to learn entity representations in a coarse-to-fine manner.
Local vs. global structure - (Foundations of Data Science) - Vocab ...
Local structure focuses on the relationships and configurations between closely related data points, while global structure encompasses broader patterns that define the overall shape or distribution of the entire dataset.
Global and local structure preserving nonnegative subspace …
2023年6月1日 · For better utilization of the global and local structure information of data, our method combines global and local similarity learning together. By adding nonnegative Lagrangian constraints to subspace clustering, the proposed method can learn data similarities and cluster indicators in an integrated optimization framework.
Global and Local Structure Preservation for Feature Selection
2013年11月7日 · In order to show this, we propose a global and local structure preservation framework for feature selection (GLSPFS) which integrates both global pairwise sample similarity and local geometric data structure to conduct feature selection.
Global and Local Structure Network for Image Classification
2023年3月20日 · In this paper, we propose a new simple and efficient convolutional neural network called global and local structure network (GLSNet) to address the problems. The network extracts the features both from the global structure and the local structure of …
