LeetCode49. Group Anagrams

Mask2former自定义数据集实现滑坡语义分割 先介绍一下这次用的数据集:Bijie Landslide Dataset,是武汉大学在Triplesat卫星上裁剪的数据集,包含770张滑坡(image、mask、dem、边界坐标txt)和2003张非滑坡数据(dem、image)。直接在ade20k修改,按照路径和设置将预处理数据放好,该步骤很快就能结束,打开的图片是全黑的,因为0和1在图片上肉眼较难区分。bijie的数据集可以直接使用,接下去的步骤是1、预处理数据。配置文件修改训练类别和训练类型,由于我们分割的是滑坡,所以进行语义分割。 阅读详情

题目描述:

将给定的一组字符串数组,按照同构词(相同字母组成的单词)分类,每组单词按照字典排序。

题目分析:

哈希。先将字符串数组按字典序排一次,再构造map<string,vector<string>> hashMap,遍历字符串数组,将数组中每一个字符串按字典序排好,作为键值,这样就能将同构词放在同一组中。

代码:
class Solution {
public:
    vector<vector<string>> groupAnagrams(vector<string>& strs) {
        int len=strs.size();
        vector<vector<string>> result;
        if(len==0){
            return result;
        }
        sort(strs.begin(),strs.end());
        map<string,vector<string>> hashMap;
        for(int i=0;i<len;i++){
            string str=strs[i];
            sort(str.begin(),str.end());
            hashMap[str].push_back(strs[i]);
        }
        map<string,vector<string>>::iterator iter=hashMap.begin();
        for(;iter!=hashMap.end();iter++){
            result.push_back(iter->second);
        }
        return result;
    }
};

【光伏风电功率预测】偏差考核每月少几十万:STL-VMD + Informer-LSTM 在某基地的落地案例

摘要:某风光一体化基地通过STL-VMD二次分解与Informer-LSTM并行残差模型,在不推翻现有预测系统的情况下,将风光功率预测的综合nRMSE降低了1.2-1.5个百分点。该方案通过分解预测误差为多个子序列,并采用不同模型处理各频段特征,显著改善了关键时段的预测精度。实施后,风电nRMSE从9.0%降至7.6%,光伏从10.2%降至8.8%,每月减少偏差考核费用30-50万元。项目经验表明,数据质量优化、参数调优及与业务目标对齐是关键成功因素,该技术路线具有可复制性,为风光基地预测精度提升提供了有效
