Dimensionality Reduction (DR) methods are a cornerstone of analyzing high dimensional data, due to their simple geometric interpretations and typically attractive computational properties. These methods capture many data features of interest, such as covariance, dynamical structure, and correlation betw...

Below are the ROC curves for all the evaluated dimensionality reduction techniques and the best performing machine learning algorithm. The value of the area under the curve is shown in the legend. Further Reading: Scaling analytics through KNIME ...
It brings a lot of information to people, at the same time, because of its sparse and redundancy, it also brings great challenges to data mining and pattern recognition. Dimensionality reduction can reduce redundancy and noise, reduce the complexity of learning algorithms, and improve the accuracy...
In this context, dimensionality reduction techniques are helpful for reducing amount of data and finding the accurate pattern form the image data. Therefore, in this paper PCA, LDA and ICA methods are studied. These techniques are the ... D. S. Kumar,Er. Ankur Chauhan - 《International Journ...

The analysis of the big volumes of data requires efficient and robust dimension reduction techniques to represent data into lower-dimensional spaces, which ease human understanding. This paper presents a study of the stability, robustness and performance of some of these dimension reduction algorithms ...
