The coenotic diversity of forests of the model region in southwestern Moscow oblast with an area of 51 500 ha has been assessed using data from field studies, remote sensing (Landsat-5 TM, Landsat-8 OLI, and TIRS), and digital terrain models of the landscape. Forest communities are classified using two different methods: eco-phytocoenotic and eco-floristic. We ...

The paper considers the problem of feature selection in the classification problem. A method for selecting informative features based on a probabilistic approach and cross-entropy metrics is proposed. Several variants of the information criterion for selecting features for a binary classification problem are considered, as well as its generalization to the case of a multiclass ...

In article possible approaches to clustering of large city schools of the Russian Federation by results of their educational activity are studied. The extent to which a school has entered a particular cluster is determined by a number of objective conditions in which schools operate. Significant indicators of conditions affecting the EGE-results in schools were identified. It is shown ...

To improve the performance of remote sensing images multiclass classification we propose two greedy algorithms of feature selection. The discriminant analysis criterion and regression coefficients are used as the measure of feature subset effectiveness in the first and second methods, respectively. The main benefit of the built algorithms is that they estimate not the individual ...

В данной работе решается задача выявления группы наиболее информативных признаков, влияющих на классификацию изображений, полученных при дистанционном зондировании Земли (ДЗЗ). Были исследованы две группы признаков: гистограммные и текстурные. Отбор информативных признаков осуществлялся с помощью метода, основанного на дискриминантном анализе и жадном добавлении признаков. Для обнаружения влияния отобранных признаков на разделимость классов была произведена классификация объектов ...

В работе исследуются два метода отбора наиболее информативных признаков для повышения эффективности классификации изображений земной поверхности, полученных при дистанционном зондировании Земли. Один из рассмотренных методов отбора признаков основан на дискриминантном анализе, другой – на построении линейной регрессионной модели. В качестве характеристик изображений используются ряд гистограммных и текстурных признаков. Экспериментальное исследование предложенных методов на изображениях из ...
