Straight-Path Flow Matching for Incomplete Multi-View Clustering
Summary
Straight-Path Flow Matching for Incomplete Multi-View Clustering introduces a novel flow-matching framework to address the challenge of clustering multi-modal data with missing views. Unlike prior end-to-end generative methods that use diffusion models and stochastic noise-to-data trajectories, this approach employs a linear interpolation path between paired view representations, replacing diffusion with deterministic probability flows. A formal analysis demonstrates that these ODE flows are inherently better suited for clustering objectives, preserving class-conditional data distributions and cluster consistency. The proposed end-to-end IMVC architecture integrates this straight-path flow-matching view completion with cluster-level and entropy-based alignment. This framework achieved new state-of-the-art performance on standard IMVC benchmarks and was accepted to ECCV 2026.
Key takeaway
For Machine Learning Engineers developing solutions for multi-modal data with missing components, consider adopting flow-matching techniques over traditional diffusion models. Your systems can achieve superior clustering performance by leveraging deterministic ODE flows, which are shown to better preserve class-conditional data distributions and maintain cluster consistency. This approach offers a more robust and accurate method for handling incomplete multi-view datasets.
