Researchers have developed a novel unsupervised multimodal clustering method (UMC) designed to improve the discovery of semantics within multimodal utterances. UMC constructs unique augmentation views for pre-training, initializing representations for subsequent clustering. It also features a dynamic sample selection strategy that uses the density of nearest neighbors to identify high-quality samples for representation learning, while also determining optimal parameters for refining this selection. This method has demonstrated significant improvements, achieving 2-7% higher scores in clustering metrics compared to existing state-of-the-art approaches on benchmark datasets. AI
