We sought to apply our extended Isomap approach to see if non-linear dimensionality reduction can find the low-dimensional embedding of the apoptosis signaling network. Extended Isomap approach involves three main steps: The Isomap algorithm first constructs a low-dimensional embedding of the apoptosis...

Non-linear dimensionality reduction techniques for unsupervised feature extraction Dimensionality reduction techniques have been regularly used for visualization of high-dimensional data sets. In this paper, reduction to d 鈮 2 is studied,... SD Backer,A Naud,P Scheunders - 《Pattern Recognition Letter...
The test time, well-defined and non-zero for all the methods, started immediately after the end of the training period and ran until the point when the output time series (one-step-ahead predictions) were computed. Note that computations of the R2 and whiteness statistics were optional post-...

线性判别分析(Linear Discriminant Analysis)简称LDA,是分类算法中的一种。 LDA通过对历史数据进行投影,以保证投影后同一类别的数据尽量靠近,不同类别的数据尽量分开。并生成线性判别模型对新生成的数据进行分离和预测。 一、与PCA的几点不同 出发思想不同。PCA主要是从特征的协方差角度,去找到比较好的投影方式,即选择...
