Question

Accepted Answer

Traditional ID-based approaches fail with cold-start items, wasting recommendation opportunities. Semantic IDs enable 3x better cold-start performance while reducing computational overhead. 256-dimensional latent space with 8 quantization levels 2048 codebook entries per quantization level SPM methods superior with larger embedding tables Use Semantic IDs for cold-start recommendation scenarios
