#IJCAI 2018 阿里妈妈广告预测算法
背景
本项目是天池的一个比赛，由阿里妈妈和天池大数据众智平台举办广告预测算法大赛，本次参赛人数多达5200多，而我们只取得了731的成绩，最遗憾的是当我们写好CNN预测结果准备上传，发现队伍被强制解散，只因为的大神队友忘记实名注册，没心很无奈，又非常不甘心，但是这就是规则，我们只有遵循的权利，难过伤心之后还是需要把整个项目进行整理总结。
目标
本次比赛以阿里电商广告为研究对象，提供了淘宝平台的海量真实交易数据，参赛选手通过人工智能技术构建预测模型预估用户的购买意向，即给定广告点击相关的用户（user）、广告商品（ad）、检索词（query）、上下文内容（context）、商店（shop）等信息的条件下预测广告产生购买行为的概率（pCVR），形式化定义为：pCVR=P(conversion=1 | query, user, ad, context
