Researchers have developed a novel framework called PromptCCD for Continual Category Discovery (CCD), which enables models to identify new categories from unlabeled data streams while retaining knowledge of previously learned concepts. The initial PromptCCD model utilizes a Gaussian Mixture Prompt (GMP) module to manage global class prototypes and dynamically estimate the number of emerging categories. Further enhancements in PromptCCD++ incorporate Part-level Prompting (PLP) modules to decompose prompt pools into specialized part-level prompts, allowing for finer-grained object-part representations and improved category discovery.
