- Abstract: One-class classification (OCC), which models one single positive class and
distinguishes it from the negative class, has been a long-standing topic with
pivotal application to realms like anomaly detection. As modern society often
deals with massive high-dimensional complex data spawned by multiple sources,
it is natural to consider OCC from the perspective of multi-view deep learning.
However, it has not been discussed by the literature and remains an unexplored
topic. Motivated by this blank, this paper makes four-fold contributions:
First, to our best knowledge, this is the first work that formally identifies
and formulates the multi-view deep OCC problem. Second, we take recent advances
in relevant areas into account and systematically devise eleven different
baseline solutions for multi-view deep OCC, which lays the foundation for
research on multi-view deep OCC. Third, to remedy the problem that limited
benchmark datasets are available for multi-view deep OCC, we extensively
collect existing public data and process them into more than 30 new multi-view
benchmark datasets via multiple means, so as to provide a publicly available
evaluation platform for multi-view deep OCC. Finally, by comprehensively
evaluating the devised solutions on benchmark datasets, we conduct a thorough
analysis on the effectiveness of the designed baselines, and hopefully provide
other researchers with beneficial guidance and insight to multi-view deep OCC.
Our data and codes are opened at https://github.com/liujiyuan13/MvDOCC-datasets
and https://github.com/liujiyuan13/MvDOCC-code respectively to facilitate
future research.

Clustering analysis plays an indispensable role in machine learning and data mining.
Deep clustering, which can learn clustering-friendly representations using deep neural networks, has been broadly applied in a wide range of clustering tasks.
Existing surveys for deep clustering mainly focus on the single-view fields and the network architectures, ignoring the complex application scenarios of clustering.

Clustering is a fundamental machine learning task which has been widely studied in the literature.
Deep Clustering, i.e., jointly optimizing the representation learning and clustering, has been proposed and hence attracted growing attention in the community.
We summarize the essential components of deep clustering and categorize existing methods by the ways they design interactions between deep representation learning and clustering.

We propose a generative partial multi-view clustering model, named as GP-MVC, to address the incomplete multi-view problem.
First, multi-view encoder networks are trained to learn common low-dimensional representations, followed by a clustering layer to capture the consistent cluster structure across multiple views.
Second, view-specific generative adversarial networks are developed to generate the missing data of one view conditioning on the shared representation given by other views.
