title: Feature selection with multi view data: A survey
abstract: This survey aims at providing a state of the art overview of feature selection and fusion strategies, which select and combine multi view features effectively to accomplish associated tasks. The existing literatures on feature selection approaches are classified into three categories including filter method, wrapper method, and embedded method. Based on the feature selection methods mentioned above, feature level fusion or known as low level fusion methodology is further investigated from the perspective of the basic concept, procedure, and applications in analysis tasks as presented in the literatures. Moreover, several distinctive issues that influence the information fusion process such as the use of correlation, confidence level, synchronization, and the optimal features are also emphasized. Finally, we present the adaptive multi view issues for further research in the area of feature selection and fusion by learning view specific weights to each view data automatically.

title: A Survey on Hybrid Feature Selection Methods in Microarray Gene Expression Data for Cancer Classification
abstract: The emergence of DNA Microarray technology has enabled researchers to analyze the expression level of thousands of genes simultaneously. The Microarray data analysis is the process of finding the most informative genes as well as remove redundant and irrelevant genes. One of the most important applications of the Microarray data analysis is cancer classification. However, the curse of dimensionality and the curse of sparsity make classifying gene expression profiles a challenging task. One of the most effective methods to overcome these challenges is feature (gene) selection. In this paper, we aim to review and compare the most recent hybrid approaches that employ bio inspired evolutionary methods as the wrapper method.

title: Survey: Feature Selection Technique Impact for Internet Traffic Classification Using Naive Bayesian
abstract: Internet traffic defines as the density of data or information presented on the Internet or in another language we can say it's a flow of data on the internet. Internet traffic classification has power to solve many network difficulties and manage different type of network problems. There are some basic functions provided to government, Internet service providers (ISPs) and network administrator through Internet traffic classification. Machine learning approaches overcome many problems of traditional approaches of internet traffic classification. In supervised approaches, we discuss five well known supervised machine learning approaches these are Naive Bayes, Feed Forward Neural Network, Bayes Net, RBF and C4.5 decision tree approach.

title: Feature selection in image analysis: a survey
abstract: Image analysis is a prolific field of research which has been broadly studied in the last decades, successfully applied to a great number of disciplines. Since the apparition of Big Data, the number of digital images is explosively growing, and a large amount of multimedia data is publicly available. Not only is it necessary to deal with this increasing number of images, but also to know which features extract from them, and feature selection can help in this scenario. The goal of this paper is to survey the most recent feature selection methods developed and/or applied to image analysis, covering the most popular fields such as image classification, image segmentation, etc. Finally, an experimental evaluation on several popular datasets using well known feature selection methods is presented, bearing in mind that the aim is not to provide the best feature selection method, but to facilitate comparative studies for the research community.

title: Performance comparison of linear and non linear feature selection methods for the analysis of large survey datasets
abstract: Large survey databases for aging related analysis are often examined to discover key factors that affect a dependent variable of interest. Typically, this analysis is performed with methods assuming linear dependencies between variables. Such assumptions however do not hold in many cases, wherein data are linked by way of non linear dependencies. This in turn requires applications of analytic methods, which are more accurate in identifying potentially non linear dependencies. Here, we objectively compared the feature selection performance of several frequently used linear selection methods and three non linear selection methods in the context of large survey data. These methods were assessed using both synthetic and real world datasets, wherein relationships between the features and dependent variables were known in advance. In contrast to linear methods, we found that the non linear methods offered better overall feature selection performance than linear methods in all usage conditions. Moreover, the performance of the non linear methods was more stable, being unaffected by the inclusion or exclusion of variables from the datasets. These properties make non linear feature selection methods a potentially preferable tool for both hypothesis driven and exploratory analyses for aging related datasets.

title: Feature Selection Algorithms for Data Mining Classification: A Survey
abstract: This study summarizes the feature selection process, its importance, different types of feature selection algorithms such as Filter, Wrapper and Hybrid. Moreover, it analyses some of the existing popular feature selection algorithms through a literature survey and also addresses the strengths and challenges of those algorithms. Methods/ Statistical Analysis: When there are many methods are in hand to be obtained, then Review of Literature is the best approach to learn about existing methods before going for a new model.  Feature selection is a predominant preprocessing strategy in Data Mining, which helps in advancing the performance of mining, by selecting only the relevant features and avoiding the redundant features. There are plenty Feature Selection algorithms developed and used by most researchers. But still it is an emerging area in machine learning to be focused for data mining and analysis process for pattern recognition. Many feature selection algorithms confront severe challenges in terms of effectiveness and efficiency, because of recent increase in data variety and velocity. Different types of feature selection algorithms are available in literature such as Filter based, Wrapper based and Hybrid algorithms. Moreover, analyses some of the existing popular feature selection algorithms through a literature survey, also addresses the strengths and challenges of those algorithms.  There is a need for an effective unified framework, which should provide feature selection for any size of dataset without noisy data, low computational complexity and highest accuracy.
