Reducing the dimensionality of data using different techniques

High-dimensional data processing is really the key issue in many systems, including content- based extraction, voice signals, fMRI analyses, electroencephalogram object detection, multimedia extraction, market-based technologies, etc. In order to enhance the system's effectiveness, the data dimensions must be minimized to a low dimensional space. Inthis paper, we analyzed linearization, nonlinear and network embedding dimensionality reduction methods. A few of these methods are ideal and used for linear data that have linear relationship between data points, and many other dimensionality reduction methods are used for nonlinear data that have nonlinear relationship among data points.From an analysis of this paper, we found that Structural Deep Network Embedding (SDNE), LINE (Large-Scale Network Embedding) and Nod۲Vec are the best techniques for dimensionality reduction in network data.Furthermore, every approach has its own characteristics and drawbacks. This study presents different methods utilized to minimize the high dimensional data into low dimensional space.
