Researchers have introduced CoFiRec, a new generative recommendation framework designed to better capture evolving user intent. Unlike previous models that compress all item attributes into a single embedding, CoFiRec decomposes item information into multiple semantic levels, from broad categories to detailed descriptions. This approach allows the model to generate item tokens from coarse to fine, progressively understanding user interests. Experiments show CoFiRec outperforms existing methods on several benchmarks, offering a novel perspective on generative recommendation. AI
