链家为顶级程序设计大赛开放真实房屋大数据
2017-08-13 16:13:18 中国经济网
国内顶级程序设计赛事——链家算法大赛暨2017计蒜之道总决赛于8月13日在链家总部开赛。为此次赛事,链家特地开放了多年积累的庞大、真实的房屋数据,选手们通过特征工程和模型算法的训练研发,对房屋价格进行估算,展现了一场房地产与大数据的精彩碰撞。

开放数据,理论联系实际生活
此次算法大赛主要面向爱好计算机科学的大、中、小学生以及社会人士,意在为计算机科学的学习者们提供一个竞技、交流的平台。
此次大赛侧重比赛内容的实用价值——对当下公众普遍关注的房屋价格进行预估。比赛的试题全部来源于链家2016年下半年至2017年8月上旬期间在北京成交的部分房源的真实数据,在对房源信息做了脱敏处理之后,要求参赛者根据房屋朝向、居室、挂牌价等公开数据进行特征工程和模型算法的训练研发,产生机器学习算法模型,分别从多个角度对一套房屋的市场价格进行预估。最终,以准确率更高的算法胜出,加入到链家房屋智能评估系统的实际算法应用中去。
(现场46位选手展开激烈交锋)
大赛现场,链家技术副总裁惠新宸在致辞中表示,链家此次举办算法大赛,开放真实的房源数据,就是希望能让专业领域的学生在学习过程中突破理论,与实际生活相结合。同时,链家也期望有更多优秀的程序设计人才加入企业,一起将数据背后的价值挖掘出来。
