Rethinking Incompleteness: Formalizing Protocol Divergence and Train-Once Learning for Robust IMVC
Researchers have introduced a new framework called CRAFT to address the challenges of incomplete data in IMVC (Incomplete Multi-View Clustering). They identified a phenomenon called "incompleteness divergence," where protocols with similar missing data rates can lead to vastly different learning outcomes and even near-random performance if the proportion of complete samples drops below a critical threshold. CRAFT, a single model trained once on complete data, achieves robustness to missing data patterns by incorporating per-sample independence and mask-aware fusion, outperforming traditional methods while significantly reducing training overhead.
