چکیده

In recent years, large scale land cover maps constructed from remotely sensed data have become important information sources for resource management. Classifiers are commonly used to predict land cover for unsampled map units; hence, they play a key role in map construction. Achieving adequate classifier accuracy is often problematic for highly variable and difficult-to-sample landscapes. This article investigates a variety of methods for improving accuracy based on 1) combining a few different classifiers, and 2) creating ensembles of many classifiers. In addition, we derive an analytic expression for the exact bagging -nearest neighbor classifier.

Land Cover Mapping Using Ensemble Feature Selection Methods

Ensemble classification is an emerging approach to land cover mapping whereby the final classification output is a result of a ‘consensus’ of classifiers. Intuitively, an ensemble system should consist of base classifiers which are diverse i.e. classifiers whose decision boundaries err differently. In this paper ensemble feature selection is used to impose diversity in ensembles. The features o...

An svm multiclassifier approach to land cover mapping

From the advent of the application of satellite imagery to land cover mapping, one of the growing areas of research interest has been in the area of image classification. Image classifiers are algorithms used to extract land cover information from satellite imagery. Most of the initial research has focussed on the development and application of algorithms to better existing and emerging classif...

Evaluation of Multiple Classifier Combination Techniques for Land Cover Classification Using Multisource Remote Sensing Data

Use of multisource remote sensing data, particularly Synthetic Aperture Radar (SAR) and optical images, can improve performance of land cover classification since many types of information are involved in the classification process. Recently, the multiple classification systems (MCS) or ensemble classifiers has been developed and increasingly used for classifying remote sensing data. It is cons...

Improving Automated Land Cover Mapping by Identifying and Eliminating Mislabeled Observations from Training Data

This paper presents a new approach to identifying and eliminating mislabeled training samples. The goal of this technique is to decrease the error of classification algorithms by improving the quality of the training data. The approach employs an ensemble of classifiers that serve as a filter for the training data. Using an n-fold cross validation, the training data is passed through the filter...
