LPP leads the Corporate Climate Crisis Awareness Study (CCA)
2024年11月15日 · LPP ranked first in this year’s 6th edition of the Corporate Climate Crisis Awareness Study (CCA). Among the 163 companies assessed in the study, LPP scored the maximum number of points, excelling in transparency and clearly defined CO2 reduction targets.
Central Centrifugal Cicatricial Alopecia and Lichen Planopilaris …
2020年12月1日 · Central centrifugal cicatricial alopecia (CCCA) and lichen planopilaris (LPP) can look identical on histopathology. Both entities demonstrate perifollicular fibrosis, peri- infundibular lymphocytic infiltrates, and reduced follicular density.
算法小课堂：Locality Preserving Projections （LPP） - 知乎专栏
lpp就是一个典型的降维算法，它的通过构建空间中各样本对之间的远近亲疏关系，并在降维投影中尽可能地去保留这样的亲疏关系，从而保留数据的局部结构。
A Least-Squares Framework for Component Analysis
2012年4月18日 · This paper proposes a unified least-squares framework to formulate many CA methods. We show how PCA, LDA, CCA, LPP, SC, and its kernel and regularized extensions correspond to a particular instance of least-squares weighted kernel reduced rank regression (LS- …
Locality preserving CCA with applications to data visualization …
2007年5月1日 · Inspired by the locality based methods, in this paper, we incorporate such an idea into CCA and propose locality preserving CCA (LPCCA) to discover the local manifold structure of the data and further apply it to data visualization and pose estimation. In addition, a fast algorithm of LPCCA is proposed for some special cases.

A least-squares framework for Component Analysis - PubMed
This paper proposes a unified least-squares framework to formulate many CA methods. We show how PCA, LDA, CCA, LPP, SC, and its kernel and regularized extensions correspond to a particular instance of least-squares weighted kernel reduced rank regression (LS--WKRRR).
PCA、LPP及两者正交改进的特征提取特征降维算法_lpp特征聚类-C…
2022年1月20日 · 本文提出了一种改进的特征提取与降维方法，即正交pcalpp，它融合了pca的全局结构保持和lpp的局部近邻结构保持，同时引入正交约束减少冗余。 通过UCI数据集的降维可视化分析，结果显示该方法在保持数据结构和聚类效果上表现优越。
数据降维：PCA、CCA、LDA、ICA的区别及适用场景 - CSDN博客
2020年12月24日 · CCA(Canonical Correlation Analysis)： 无监督学习，对两组变量降维，找到一个最优相关子空间进行相关性分析。 应用：问卷调查中变量的相关性分析、跨模态学习。 LDA： 有监督学习，学习一个可分性最好的投影方向。相当于是白化(whitening) + PCA，得到的是假设条 …
