摘要:

聚类和预测分别是无监督学习和监督学习的两个主要任务。尽管机器学习的许多最新进展都围绕着这两个任务,但它们之间相互依存、互利互惠的关系却很少被探索。人们可以合理地期望适当地聚类数据将有助于下游预测任务,相反,下游任务的更好预测性能可能会为更合适的聚类策略提供信息。在这项工作中,我们专注于这种互利关系的后半部分。为此,我们引入了深度目标导向聚类(DGC),这是一个概率框架,它通过边信息和无监督建模的固有数据结构,以端到端的方式联合使用监督来聚类数据。我们通过实现与最先进水平相当的预测精度,同时更重要的是,在我们的设置中,同时学习一致的聚类策略,在一系列数据集上展示了我们的模型的有效性。

英文摘要:

Clustering and prediction are two primary tasks in the fields of unsupervised and supervised learning, respectively. Although much of the recent advances in machine learning have been centered around those two tasks, the interdependent, mutually beneficial relationship between them is rarely explored. One could reasonably expect appropriately clustering the data would aid the downstream prediction task and, conversely, a better prediction performance for the downstream task could potentially inform a more appropriate clustering strategy. In this work, we focus on the latter part of this mutually beneficial relationship. To this end, we introduce Deep Goal-Oriented Clustering (DGC), a probabilistic framework that clusters the data by jointly using supervision via side-information and unsupervised modeling of the inherent data structure in an end-to-end fashion. We show the effectiveness of our model on a range of datasets by achieving prediction accuracies comparable to the state-of-the-art, while, more importantly in our setting, simultaneously learning congruent clustering strategies.
