摘要:

我们建议使用概率编程技术来解决推荐算法中的恶意用户识别问题。概率编程提供了优于其他技术的许多优点,包括但不限于提供恶意用户在结构化模型下如何行动的分解表示,以及允许量化恶意用户造成的损害。我们展示了恶意用户识别实验,使用一个简单的推荐算法进行交互的常规和恶意用户的模型,并提供了一种新的基于模拟的措施,用于量化用户或用户组对其动态的影响。

英文摘要:

We propose the use of probabilistic programming techniques to tackle the malicious user identification problem in a recommendation algorithm. Probabilistic programming provides numerous advantages over other techniques, including but not limited to providing a disentangled representation of how malicious users acted under a structured model, as well as allowing for the quantification of damage caused by malicious users. We show experiments in malicious user identification using a model of regular and malicious users interacting with a simple recommendation algorithm, and provide a novel simulation-based measure for quantifying the effects of a user or group of users on its dynamics.
