Definition
Multimodal representation learning involves training models to process and integrate information from different types of data sources, such as text, images, audio, and video, into a shared latent space. By aligning these diverse inputs, the model can capture complementary relationships between modalities, leading to more robust and generalizable features. This approach is crucial for tasks requiring cross-modal understanding, enabling systems to leverage the strengths of each modality to improve overall performance and contextual awareness.
