arXiv:2601.06572v4 Announce Type: replace-cross Abstract: Multimodal variational autoencoders (VAEs) are widely used for weakly supervised generative learning with multiple modalities. Predominant methods aggregate unimodal inference distributions using either a product of experts (PoE), a mixture of experts (MoE), or their combinations to approximate the joint posterior. In this work, we revisit multimodal inference through the lens of probabilistic opinion pooling, an optimization-based approach. We start from H\"older pooling with $\alpha=0.5$, which corresponds to the unique symmetric memb
This paper represents continued academic advancement in multimodal AI, addressing a core challenge in combining information from diverse data sources efficiently.
Improved multimodal VAEs enhance AI's ability to learn from heterogeneous data, leading to more robust and versatile generative models for various applications.
The proposed Hellinger Multimodal VAE offers a novel approach to aggregating unimodal inference distributions, potentially leading to more accurate and efficient multimodal learning.
