- Abstract: Modern Review Helpfulness Prediction systems are dependent upon multiple
modalities, typically texts and images. Unfortunately, those contemporary
approaches pay scarce attention to polish representations of cross-modal
relations and tend to suffer from inferior optimization. This might cause harm
to model's predictions in numerous cases. To overcome the aforementioned
issues, we propose Multimodal Contrastive Learning for Multimodal Review
Helpfulness Prediction (MRHP) problem, concentrating on mutual information
between input modalities to explicitly elaborate cross-modal relations. In
addition, we introduce Adaptive Weighting scheme for our contrastive learning
approach in order to increase flexibility in optimization. Lastly, we propose
Multimodal Interaction module to address the unalignment nature of multimodal
data, thereby assisting the model in producing more reasonable multimodal
representations. Experimental results show that our method outperforms prior
baselines and achieves state-of-the-art results on two publicly available
benchmark datasets for MRHP problem.

Multimodal learning is expected to boost model performance by integrating information from different modalities.
The widely-used joint training strategy leads to imbalanced and under-optimized uni-modal representations.
We propose On-the-fly Prediction Modulation (OPM) and On-the-fly Gradient Modulation (OGM) strategies to modulate the optimization of each modality.

Multimodal variational autoencoders (VAEs) aim to capture shared latent representations by integrating information from different data modalities.
A significant challenge is accurately inferring representations from any subset of modalities without training an impractical number of inference networks for all possible modality combinations.
We introduce multimodal iterative amortized inference, an iterative refinement mechanism within the multimodal VAE framework.

Specifically, we first utilize an optimization strategy based on sharpness aware minimization (SAM) to smooth the learning objective during the forward phase.
Then, with the help of the geometry property of SAM, we propose a gradient modification strategy to impose the influence between different modalities during the backward phase.
