机器学习降维算法一:PCA (Principal Component Analysis) 引言: 机器学习领域中所谓的降维就是指采用某种映射方法,将原高维空间中的数据点映射到低维度的空间中。降维的本质是学习一个映射函数 f : x->y,其中x是原始数据点的表达,目前最多使用向量表达形式。 y是数据点映射后的低维向量表达,通常y的维度小于x...

The majority of Raman spectra analysis works have been based on classical machine learning methods. Therefore, it has always been crucial to reduce the feature space. In this regard, principal component analysis (PCA) has been the most prominent method for feature reduction, to the extent that ...

In the past few years, tensor robust principal component analysis (TRPCA) which is based on tensor singular value decomposition (t-SVD) has got a lot of attention in recovering low-rank tensor corrupted by sparse noise. However, most TRPCA methods only consider the global structure of the imag...
