推荐系统中的人机交互

Human Interaction with Recommendation Systems

Stanford University(斯坦福大学);Google Brain(谷歌大脑)

Sven Schmit, Carlos Riquelme

摘要:

许多推荐算法依赖于用户数据来生成推荐。但是,这些建议也会影响从未来用户那里获得的数据。这项工作旨在了解这种动态相互作用的影响。我们提出了一个简单的模型,随着时间的推移,不同的偏好的用户到达。基于这个模型,我们证明了天真的估计,即那些忽略这个反馈回路,是不一致的。我们表明,相合估计量是有效的近视剂的存在。我们的结果进行了验证,使用广泛的模拟。

英文摘要:

Many recommendation algorithms rely on user data to generate recommendations. However, these recommendations also affect the data obtained from future users. This work aims to understand the effects of this dynamic interaction. We propose a simple model where users with heterogeneous preferences arrive over time. Based on this model, we prove that naive estimators, i.e. those which ignore this feedback loop, are not consistent. We show that consistent estimators are efficient in the presence of myopic agents. Our results are validated using extensive simulations.
