赛题介绍

芒果TV-第二届“马栏山杯”国际音视频算法大赛-防盗链 随着业务的发展,芒果的视频内容也深受网友的喜欢,不少视频网站和应用开始盗播芒果的视频内容,盗链网站不经过芒果TV的前端系统,跳过广告播放,且消耗大量的服务器、带宽资源,直接给公司带来了巨大的经济损失,因此防盗链在日常运营中显得尤为重要。如何从海量日志中识别出盗链行为,并进行有效拦截,也是防盗链工作的核心。 比赛网址:https://challenge.ai.mgtv.com/contest/detail/7

 

模型介绍

  • 对原始特征进行LabelEncoder编码保存为feather文件
  • 构建 group_feature、count_feature、count_time_feature、cumcount_time_feature、cumcount_feature、cumcountratio_feature、diff_feature、category_encoders_feature,对每类特征加原始特征进行LightGBM建模得到特征重要性
  • 汇总各类特征重要性后分别取前50、100、150、200、250个特征进行LightGBM建模,提交200个特征结果B榜得分0.5174

 

代码

python preprocess.py # 原始数据文件放入/data文件夹中,处理原始数据

python feature_engineering.py # 特征工程,单个特征保存为feather文件

python main.py # 模型训练,按日期排序,最后两天数据作为线下验证集数据
