Incomplete multi-view clustering (IMVC) has gained increasing attention due to its ability to analyze incomplete multi-view data.Despite deep IMVC methods achieved significant progress, they still face two challenges: (I) The method-specific inseparable designs limit their application. (II) Non-independent and identically distributed (Non-IID) missing patterns has not been considered and caused degeneration. To address these issues, we propose a novel unified framework that bridges from deep MVC to deep IMVC, while emphasizing the robustness against Non-IID missing patterns. Our framework has a two-stage process: (I) Multi-view learning on complete data, where our framework is modularly established to be compatible with different multi-view interaction objectives. (II) Transfer learning and clustering on incomplete data, where we propose a multi-view domain adversarial learning method to improve the model robustness to Non-IID missing patterns. Moreover, an intra-view and inter-view imputation strategy is introduced for more reliable clustering.Based on our unified framework, we easily construct multiple IMVC instances and extensive experiments verified their clustering effectiveness.
