LoopFM: Learning frOm HistOrical RePresentations of Foundation Model for Recommendation

arXiv:2605.29280v1 Announce Type: new Abstract: Knowledge distillation (KD) transfers a single scalar prediction from a large foundation model (FM) to compact vertical models (VMs), suffering from diminishing transfer ratio -- the fraction of FM improvement captured by the VM -- as a single scalar cannot convey the rich intermediate knowledge that larger FMs learn. To address this bottleneck, we propose LoopFM (Learning frOm HistOrical ReP*resentations of FM), a framework that opens a high-bandwidth transfer channel by structuring FM intermediate embeddings as input features (e.g., user histor

Why this matters
Why now

The increasing scale and complexity of foundation models necessitate more efficient knowledge transfer methods as their real-world deployment becomes ubiquitous.

Why it’s important

This breakthrough improves the efficiency of deploying large foundation models into compact vertical models, making advanced AI capabilities more accessible and performant for specialized tasks.

What changes

Knowledge transfer from large foundation models can now leverage rich intermediate embeddings instead of just scalar predictions, significantly improving the performance of smaller derived models.
