Researchers have developed a new method called Spherical Centroid Aggregation with Learned Adaptive Relevance (SCALAR) to improve multimodal retrieval systems. Unlike previous methods that treated all data types equally, SCALAR assigns adaptive weights to different modalities like video, audio, and text based on their relevance to a query. This approach, which uses a small number of trainable parameters, has shown significant improvements in retrieval accuracy across multiple benchmarks, outperforming prior aggregators and even achieving state-of-the-art results on text-to-video retrieval.
