arXiv:2606.12245v1 Announce Type: cross Abstract: Cold-start item recommendation remains a persistent challenge in real-world systems due to the absence of interaction histories. While prior models attempt to bridge this gap using item content features, they universally suffer from the \textbf{seesaw dilemma}: enhancing performance for cold items inevitably degrades performance for warm items, and vice versa. We identify that this dilemma stems from a fundamental \textbf{distributional disparity}: warm item embeddings occupy a complex ``behavioral manifold" shaped by rich interaction signals,
The increasing sophistication of generative AI models, specifically diffusion models, is enabling new approaches to long-standing challenges in recommendation systems.
Improving cold-start recommendations can significantly enhance user experience, accelerate product adoption, and unlock value in domains with sparse interaction data.
This research suggests a potential method to overcome the 'seesaw dilemma' in recommendation systems, allowing for better performance for both new (cold) and established (warm) items simultaneously.
