• MFLI eliminates ANN search at serving time by using learned hierarchical indices directly to identify relevant items.method 90%
• MFLI constructs a multifaceted hierarchical codebook via residual quantization of item embeddings and co-trains the codebook with the embeddings.method 90%
• MFLI introduces an efficient multifaceted indexing structure and mechanisms that support real-time updates.technical 85%
• Traditional ANN-based retrieval has a limitation where item embeddings and their indices are learned in separate stages, yielding suboptimal retrieval quality for newly created items.limitation 85%
• Traditional ANN-based retrieval incurs substantial computation cost at industry scale because it must be run for every request despite offering sublinear query time.limitation 85%
