arXiv:2606.15743v1 Announce Type: new Abstract: This paper addresses the missing-modality challenge in multi-modal learning by introducing Unsupervised Learning for Missing Modalities in Multi-Modal Learning (UL4M4), a flexible framework that imputes missing feature embeddings in a task-independent manner before supervised prediction. We propose modality-specific normalization and a novel partial-modality distance metric to enable fair clustering of incomplete observations, capturing cross-modal structures while preserving scale-invariance across varying dimensionalities and modality counts.

The proliferation of multimodal data and the inherent challenge of incomplete datasets highlight the immediate need for robust missing modality solutions in AI. Recent advancements in unsupervised learning are enabling more sophisticated approaches to such problems.
This development addresses a fundamental limitation in multimodal AI, enabling more robust and versatile systems that can operate effectively even with imperfect data, a common real-world scenario. It accelerates the deployment of AI in complex environments.
Multimodal AI systems can now more reliably process incomplete datasets, reducing data preparation overhead and improving model performance in real-world applications where all modalities are not always available. This expands the practical applicability of such AI.

AI models become more resilient to missing input data, improving robustness and real-world deployment success.
This could lead to a faster adoption of multimodal AI in domains previously hindered by data completeness issues, such as health or environmental monitoring.
The increased utility of multimodal AI might accelerate the development of more general-purpose AI agents capable of understanding and interacting with complex, incomplete environments.
