Paper Reading:ControlBurn-Feature Selection by Sparse Forests

针对存在大量相关特征时重要特征的影响被削弱的问题,本文设计了一种通过稀疏森林来消除相关偏差的特征选择算法 ControlBurn。首先使用套袋和提升等方法生成森林,然后通过一个平衡特征稀疏性和预测性能的组 LASSO 惩罚目标为每棵树选择稀疏权值,从而减少树的数量。与 Wrapper 特征选择方法不... ......

Paper Reading: A pareto-based ensemble of feature selection algorithms

本文将集成特征选择问题建模为具有两个目标的帕累托优化问题,提出一种类型的异构集成特征选择算法 PEFS。首先采用两种聚合方法对四种不同 FS 方法得到的结果进行组合,接着使用双目标优化来评估这些结果,最后根据非优势特征在双目标空间中的拥挤距离进行排序。该方法平衡了关联度和冗余性两种不同的 FS 方法... ......

MYSQL Replace into 和 Insert into duplicate key update 对比

有些同学对MYSQL中两个看似相同功能的语句,在使用中感到疑惑,到底是功能重复还是各有各自的特点,我们需要弄清楚,并在合适的场合对他们加以利用。 我们通过几个操作来详细了解一下他们的使用方式和异同点 情况一, 判断当前ID 是否存在 ID = 1 的记录,如果有就更新数据,如果没有则插入记录 这里如 ......

前端往读取到的压缩文件里添加文件,针对了shapefile(shp)压缩文件里没有.cfg导致中文乱码的情况

前端使用shpjs库处理shp压缩文件(.zip),在没有.cpg文件的情况下会出现中文乱码问题。.cpg文件中定义了字符编码的格式,通过shp.js源码,可以看出是parseDbf这个库的函数解析dnf文件需要获取字符编码格式(encoding),最简单的方法是将整个shpjs模块复制到src下面 ......

git学习笔记(十一):Feature分支

> 新旧更迭,不辞旧来迎新。 > 每添加一个新功能,最好新建一个feature分支在上边开发,完成后合并,最后删除这一分支。 所以正常操作就是新建分支,进入新分支,编写代码,提交代码,切回主分支,准备合并。 如果忽然这个功能不需要了,要如何销毁这一分支呢? 直接使用git branch -d fea ......

FOSTER:Feature Boosting and Compression for Class-Incremental Learning论文阅读笔记

## 摘要 先前的类增量学习方法要么难以在稳定性-可塑性之间取得较好的平衡,要么会带来较大的计算/存储开销。受gradient boosting的启发,作者提出了一种新型的两阶段学习范式FOSTER,以逐步适应目标模型和先前的集合模型之间的残差,使得该模型能够自适应地学习新的类别。具体来说,作者首先 ......

考虑枚举最大的字母所处的位置 $i$ 作为端点和最小的字母 $j$。 然后就有记录一下前缀出现次数 $cnt$,枚举一个区间。 $$cnt_{i, ch_i} - cnt_{i, j} - (cnt_{i',ch_i} -cnt_{i', j})$$ 求这个式子最大值。显然这两个式子相似,记录一下关 ......
