Researchers have developed a new multimodal deep generative model designed to tackle class imbalance in semi-supervised learning scenarios. This model utilizes separate encoders for different data modalities, sharing latent variables and employing a product-of-experts method for simplified posterior computation. To better handle imbalanced data, it incorporates Student's t-distributions instead of standard Gaussians and introduces a novel objective function based on gamma-power divergence for training. AI
