Deep Incomplete Multi-View Clustering via Hierarchical Imputation and Alignment

Jian Li, Lusi Li, Rui Ning, Yiming Du, Ziyu Wang

Hierarchical imputation of missing cluster assignments via cross-view similarity followed by feature reconstruction from intra-cluster statistics allows accurate shared clustering from partially observed multi-view data.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments on benchmarks demonstrate that our framework achieves superior performance under varying levels of missingness.

C2weakest assumption

That estimating missing cluster assignments from cross-view contrastive similarity and reconstructing features from intra-cluster statistics introduces no systematic bias and preserves semantic consistency.

C3one line summary

DIMVC-HIA is a deep method for clustering multi-view data with missing views by hierarchically imputing assignments and features then aligning clusters for consistency and compactness.
