论文摘要
在他们的工作中，Dean，Rich和Recht创建了一个模型，以研究建议系统中项目的可用性和可用性。我们使用Marx，Pin Calmon和Ustun的预测多重性定义来检查该模型的不同变化，使用两个模型参数的不同值。对其模型的成对比较表明，这些模型中的大多数在可用性的差异和歧义方面产生非常相似的结果，并且只有在某些情况下，可用性集有很大差异。
In their work, Dean, Rich, and Recht create a model to research recourse and availability of items in a recommender system. We used the definition of predictive multiplicity by Marx, Pin Calmon, and Ustun to examine different variations of this model, using different values for two model parameters. Pairwise comparison of their models show, that most of these models produce very similar results in terms of discrepancy and ambiguity for the availability and only in some cases the availability sets differ significantly.
