Aiming at the characteristics of early fire information,a least squares wavelet support vector machine(LS-WSVM) multi-class classification method based on binary tree was presented.
针对早期火灾信息特点,提出了一种基于二叉树的最小二乘小波支持向量机(Least squareswavelet support vector machine,LS-WSVM)多类分类方法。
Nine scenarios were run by the LANDIS model under three fire conditions (no fire simulating, fire return interval of 150 years and fire return interval of 325 years) and three planting strategies(no planting; Larix gmelini planting and Pinus sylvestris var.
