Latent World Recovery for Multimodal Learning with Missing Modalities

arXiv:2606.12362v1 Announce Type: new Abstract: We study multimodal learning under missing modalities, with particular motivation from bioscience applications in which heterogeneous modalities are often only partially available when decisions need to be made. We propose Latent World Recovery (LWR), a framework built on two key ideas: (i) modality-specific embeddings from different modalities are aligned in a shared latent space, and (ii) a unified representation is constructed by fusing only the embeddings of the modalities that are actually available at both training and inference time.

Why this matters
Why now

The increasing complexity and resource demands of real-world AI applications, particularly in fields with inherently incomplete data like bioscience, necessitate robust solutions for multimodal learning with missing information.

Why it’s important

This research addresses a fundamental challenge in applying multimodal AI to high-stakes domains, enabling more resilient and reliable AI systems where data scarcity or partial availability is common.

What changes

The proposed Latent World Recovery framework offers a new methodological approach for building AI models that can effectively learn and infer from incomplete multimodal datasets, potentially accelerating AI adoption in data-constrained environments.
