Image Reduction Using Assorted Dimensionality Reduction Techniques
Dimensionality reduction is the mapping of data from a high dimensional space to a lower dimension space such that the result obtained by analyzing the reduced dataset is a good approximation to the result obtained by analyzing the original data set. There are several dimensionality reduction approaches which include Random Projections, Principal Component Analysis, the Variance approach, LSA-T...
متن کاملSensitivity to parameter and data variations in dimensionality reduction techniques
Dimensionality reduction techniques aim at representing highdimensional data in a meaningful and lower-dimensional space, improving the human comprehension and interpretation of data. In recent years, newer nonlinear techniques have been proposed in order to address the limitation of linear techniques. This paper presents a study of the stability of some of these dimensionality reduction techni...
متن کاملAnalysis of unsupervised dimensionality reduction techniques
Domains such as text, images etc contain large amounts of redundancies and ambiguities among the attributes which result in considerable noise effects (i.e. the data is high dimension). Retrieving the data from high dimensional datasets is a big challenge. Dimensionality reduction techniques have been a successful avenue for automatically extracting the latent concepts by removing the noise and...
متن کاملStudy on Dimensionality Reduction Techniques and Applications
Data is not collected only for data mining. Data accumulates in an unprecedented speed. Data preprocessing is an important part for effective machine learning and data mining. Data mining is discovering interesting knowledge from large amounts of data, which is the integral part of the KDD (Knowledge Discovery in Databases), which is the overall process of converting raw data into useful inform...
متن کاملDimensionality Reduction for Data Visualization
Dimensionality reduction is one of the basic operations in the toolbox of data-analysts and designers of machine learning and pattern recognition systems. Given a large set of measured variables but few observations, an obvious idea is to reduce the degrees of freedom in the measurements by representing them with a smaller set of more “condensed” variables. Another reason for reducing the dimen...
