The Wavelet method is used [4] for feature extraction and dimensionality reduction of microarray data.
Although the detection accuracy can be improved by increasing 2D Gabor filters with different parameters, the feature dimensionality will be increased and the time consuming become large.
In the third section, we explain the dimensionality reduction technique t-SNE in detail and describe how the Random Forest based dissimilarity measure is computed and incorporated in this method.
Singular value decomposition is a popular dimensionality reduction method, through which one can get a projection: f : X [right arrow] [R.
Comparing the performance of the classifiers before and after the dimensionality reduction used the paired T-test.
The hubness phenomenon [1] has recently come into focus as an important aspect of the curse of dimensionality that affects many instance-based machine learning systems.
This data management text from Lu, Plataniotis, and Venetsanopoulos focuses on efficient dimensionality reduction of high-dimensional data sets with acceptable fidelity.
Inspired by above analyses, a dimensionality reduction algorithm called Tensor Graph-based Linear Discriminant Analysis (TGbLDA) is proposed in the paper.
1(c) can well exhibit the double-hump characteristic, and the dimensionality of 1D range cut is much lower than the original image, so people usually take 1D range cut as the feature vector.
Transformation techniques that are usually applied for dimensionality reduction include Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA) and Nonlinear Discriminant Analysis (NLDA) [3].
The first challenge is to find the optimum dimensionality reduction technique that produces meaningful visualization.
