论文摘要
我们提出了一项研究，以检测友谊的友谊，以及从智能手机位置数据收集的兄弟会成员的变化。我们提取了一系列的共同座位功能和建立分类器，可检测友谊，并以比随机基线高30％的友谊。我们设计了交叉验证架构以在特定的应用程序设置中测试模型性能，发现看到新的二元组和暂时性变化是可靠的。
We present a study to detect friendship, its strength, and its change from smartphone location data collectedamong members of a fraternity. We extract a rich set of co-location features and build classifiers that detectfriendships and close friendship at 30% above a random baseline. We design cross-validation schema to testour model performance in specific application settings, finding it robust to seeing new dyads and to temporalvariance.
