چکیده

Generation of massive data is increasing in big industries due to the evolution modern technologies. The include source from sensors, Internet Things, digital and social media. In particular, these systems consist extraction, preprocessing, integration, analysis, visualization mechanism. encountered sources are redundant, incomplete conflict. Moreover, real time applications, it a tedious process for interpretation all different sources. this paper, gathered preprocessed handle issues such as For that, proposed have generalized dimensionality reduction technique called Shrinkage Linear Discriminate Analysis (SLDA). As result, (LDA) will improve performance classifier with generalization. Even though, classifier, irrelevant features get degraded by system further. Hence, relevant most important selected using Pearson correlation-based feature selection which selects subset correlated improving classification system. classified Quadratic-Gaussian Discriminant (QGDA) classifier. techniques tested localization cover sets machine learning University California Irvine (UCI) repository. addition on datasets evaluated evaluation metrics compared other similar methods prove efficiency It has achieved better performance. acquired accuracy over 91% experiment datasets. Based results terms training percentage mapper, meaningful conclude that method could be used classification.

Fisher’s Linear Discriminant Analysis for Weather Data by reproducing kernel Hilbert spaces framework

Recently with science and technology development, data with functional nature are easy to collect. Hence, statistical analysis of such data is of great importance. Similar to multivariate analysis, linear combinations of random variables have a key role in functional analysis. The role of Theory of Reproducing Kernel Hilbert Spaces is very important in this content. In this paper we study a gen...

Linear Discriminant Analysis for Subclustered Data

Linear discriminant analysis (LDA) is a widely-used feature extraction method in classification. However, the original LDA has limitations due to the assumption of a unimodal structure for each cluster, which is not satisfied in many applications such as facial image data when variations, e.g. angle and illumination, can significantly influence the images. In this paper, we propose a novel meth...

Linear Discriminant Analysis in Document Classification

Document representation using the bag-of-words approach may require bringing the dimensionality of the representation down in order to be able to make effective use of various statistical classification methods. Latent Semantic Indexing (LSI) is one such method that is based on eigendecomposition of the covariance of the document-term matrix. Another often used approach is to select a small num...
