Researchers have developed a unified framework to understand when cross-modal alignment (CA) and cross-modal prediction (CP) are effective for multimodal learning. Their model identifies four distinct regimes: Both, CA only, CP only, and Neither, based on signal-to-noise ratios and cross-modal correlations. A data-driven procedure allows practitioners to diagnose their specific multimodal problem and select the appropriate objective before commencing training, potentially avoiding harmful cross-modal training in the 'Neither' regime.
