openLayer移除Feature时报错
问题 在功能中,点击起点按钮则在地图中标记“起点”图标,当再次点击起点按钮时需要先清空之前的“起点”图标,再重新添加。 但此时控制台报错了: 错误代码: 在添加点之前,先执行了vectorSource.clear(),导致remove时,vectorSource.getFeatures()其实是空数 ......

Paper Reading: Sample and feature selecting based ensemble learning for imbalanced problems
为了克服现有集成方法的缺点,本文提出一种新的混合集成策略——样本和特征选择混合集成学习 SFSHEL。SFSHEL 考虑基于聚类的分层对大多数样本进行欠采样,并采用滑动窗口机制同时生成多样性的特征子集。然后将经过验证训练的权重分配给不同的基学习器,最后 SFSHEL 通过加权投票进行预测。SFSHE... ......
WPF绘图(一):几何(Geometry)与形状(Shape)
1. Geometry 在数学中,我们可以用一个方程描述圆:x2+y2=25。这个方程描述的是,一个半径为5,中心点在(0,0)的圆。这种纯数学的描述就是Geometry(几何)。 但此时,这个“圆”我们是看不见,摸不着的。如果想要看到这个几何图形,就必须用画笔,颜色等信息,去“绘制”它。 .Net ......

java中的异步任务处理和Feature接口
简介 Java并发包提供了一套框架,大大简化了执行异步任务所需要的开发。框架引入了“执行服务”的概念,封装了任务执行的细节,对任务提交者而言,他可以关注任务本身,如提交任务、获取结果、取消任务。而不用关注任务执行的细节。 基本接口 ①Runnable和Callable: 表示要执行的任务 ②Exce ......
