基于异质多视图主动学习的高光谱地物分类
HYPERSPECTRAL IMAGE CLASSIFICATION BASED ON HETEROGENEOUS MULTI-VIEW ACTIVE LEARNING
摘要
Abstract
Hyperspectral remote sensing images have multi-source, heterogeneous characteristics, but face the problems of less samples and labeling difficulty.This paper intent to extract multiple types of attribute features,including spatial shape and texture,etc.,to construct multi-view and study the heterogeneous multi-view based active learning for hyperspectral image classification.Two main issues were included: 1)a new query strategy based on the minimum posteriori probability difference(MPPD)for multi-view active learning was proposed.Each view was used to predict the conditional probability of each sample according to the multinomial logistical regression classifier; the posterior probability of each sample under the multi-view was calculated according to the full probability formula;the samples with the minimum difference in posterior probability were selected as the most informative ones.2)A heterogeneous view generation strategy was proposed based on the multi-scale spatial shape and texture features.The experimental results showed that the proposed algorithm could speed up the convergence of learning functions and improved the predictive performance of learners with a small number of labeled samples with large information content.关键词
