Among existing deep clustering techniques, autoencoder-based methods are the most prevalent ones. While they achieve promising clustering results, they suffer from an inherent conflict between preserving details, as expressed by the reconstruction loss, and finding similar groups by ignoring details, as expressed by the clustering loss. This conflict leads to brittle training procedures, dependence on trade-off hyperparameters and less interpretable results. We propose our framework, ACe\/DeC, that is compatible with Autoencoder Centroid based Deep Clustering methods and automatically learns a latent representation consisting of two separate spaces. The clustering space captures all cluster-specific information and the shared space explains general variation in the data. This separation resolves the above mentioned conflict and allows our method to learn both detailed reconstructions and cluster specific abstractions.\n\nWe evaluate our framework with extensive experiments to show several benefits: (1) cluster performance \u2013 on various data sets we outperform relevant baselines; (2) no hyperparameter tuning \u2013 this improved performance is achieved without introducing new clustering specific hyperparameters; (3) interpretability \u2013 isolating the cluster specific information in a separate space is advantageous for data exploration and interpreting the clustering results; and (4) dimensionality of the embedded space \u2013 we automatically learn a low dimensional space for clustering.\n\nOur ACe\/DeC framework isolates cluster information, increases stability and interpretability, while improving cluster performance.<\/jats:p>","DOI":"10.24963\/ijcai.2021\/389","type":"proceedings-article","created":{"date-parts":[[2021,8,11]],"date-time":"2021-08-11T11:00:49Z","timestamp":1628679649000},"page":"2826-2832","source":"Crossref","is-referenced-by-count":8,"title":["Details (Don't) Matter: Isolating Cluster Information in Deep Embedded Spaces"],"prefix":"10.24963","author":[{"given":"Lukas","family":"Miklautz","sequence":"first","affiliation":[{"name":"Faculty of Computer Science, University of Vienna, Vienna, Austria"}]},{"given":"Lena G.
