摘要:

预测用户响应是计算广告中的核心机器学习任务之一。领域感知因子分解机(FFM)最近被确立为解决该问题的最先进方法,特别是赢得了两次Kaggle挑战。本文提出了一些结果,从实现这种方法在生产系统中预测点击率和转化率的显示广告,并表明这种方法不仅是有效的赢得挑战,但在现实世界中的预测系统也是有价值的。我们还讨论了一些具体的挑战和解决方案,以减少训练时间,即使用创新的播种算法和分布式学习机制。

英文摘要:

Predicting user response is one of the core machine learning tasks in computational advertising. Field-aware Factorization Machines (FFM) have recently been established as a state-of-the-art method for that problem and in particular won two Kaggle challenges. This paper presents some results from implementing this method in a production system that predicts click-through and conversion rates for display advertising and shows that this method it is not only effective to win challenges but is also valuable in a real-world prediction system. We also discuss some specific challenges and solutions to reduce the training time, namely the use of an innovative seeding algorithm and a distributed learning mechanism.
