摘要:

对齐视图表示的分布是当今用于深度多视图聚类的最新模型的核心组件。然而,我们发现了几个缺点,天真地对齐表示分布。我们证明,这些缺点都导致在表示空间中的可分离的集群,并抑制模型的能力,优先考虑的意见。基于这些观察,我们开发了一个简单的基线模型,用于深度多视图聚类。我们的基线模型完全避免了表示对齐,同时表现类似于或优于当前的最新技术水平。我们还通过添加对比学习组件来扩展我们的基线模型。这引入了一个选择性对齐过程,保留了模型对视图进行优先级排序的能力。我们的实验表明,对比学习组件增强了基线模型,在几个数据集上大幅改善了当前的最新技术水平。

英文摘要:

Aligning distributions of view representations is a core component of today's state of the art models for deep multi-view clustering. However, we identify several drawbacks with naïvely aligning representation distributions. We demonstrate that these drawbacks both lead to less separable clusters in the representation space, and inhibit the model's ability to prioritize views. Based on these observations, we develop a simple baseline model for deep multi-view clustering. Our baseline model avoids representation alignment altogether, while performing similar to, or better than, the current state of the art. We also expand our baseline model by adding a contrastive learning component. This introduces a selective alignment procedure that preserves the model's ability to prioritize views. Our experiments show that the contrastive learning component enhances the baseline model, improving on the current state of the art by a large margin on several datasets.
