Reasoning over Semantic IDs Enhances Generative Recommendation
📰 ArXiv cs.AI
Using Semantic IDs with pretrained LLMs improves generative recommendation by enabling efficient decoding over large item corpora
Action Steps
- Formulate sequential recommendation as autoregressive generation over a unified token space
- Represent each item with a compact sequence of discrete tokens, namely Semantic IDs (SIDs)
- Leverage pretrained LLMs to generate recommendations based on SIDs
- Evaluate the performance of the SID-based formulation on large-scale item corpora
Who Needs to Know This
AI engineers and researchers on a team can benefit from this approach as it enhances the performance of generative recommendation systems, while product managers can leverage it to improve user experience
