Multimodal-informax (MMIM) synthesizes fusion results from multi-modality input through a two-level mutual information (MI) maximization. We use BA (Barber-Agakov) lower bound and contrastive predictive coding as the target function to be maximized. To facilitate the computation, we design an entropy estimation module with associated history data memory to facilitate the computation of BA lower bound and the training process.
