摘要
为了建立更准确、高效的烟叶产地识别模型,提出了基于自适应遗传算法的修剪随机森林算法(AGARFP)。该算法根据种群的进化程度,适配不同的选择算子;然后利用改进的自适应遗传算法对随机森林进行修剪。实验选择5个产区的样本构建烟叶产地识别模型,以产地识别准确率作为算法优劣的衡量标准。实验结果表明,AGARFP分类准确率为94.67%,分类效果优于其他方法,从而证明了所提算法的有效性。
Abstract
In order to establish a more accurate and efficient identification model of tobacco origin, a random forest pruning algorithm based on adaptive genetic algorithm (AGARFP) is proposed. According to evolution degree of groups, the proposed algorithm can adapt to different selection operators; then, by utilizing the improved adaptive genetic algorithm, random forest pruning can be conducted. The samples of five producing areas are selected to build an identification model for tobacco origin, the precision of origin identification is used as the standard to weigh the pros and cons of the algorithm. Experimental results show that the classification precision of AGARFP can be as high as 94.67%, the classification effects of AGARFP are superior to that of the comparative methods, thus the effectiveness of the proposed algorithm is demonstrated.
