Federated Semantic Residuals for Multimodal Recommendation

Zhiwei Li, Guodong Long, Chengqi Zhang +1

Federated Recommendation Systems (FedRSs) learn collaborative scores from interaction histories on device and rank items by them, so a higher score means a higher rank. Item text a…

Symmetric Bases and $ℓ^{p}$ Embeddings in Musielak--Orlicz Sequence Spaces under $δ_{2}$

Valentin Georgiev, Boyan Zlatanov

We study isomorphic embeddings into Musielak-Orlicz sequence spaces $\ell_Φ$, where the normalized generating sequence $Φ=\{ϕ_n\}$ satisfies the $δ_2$ condition. Using admiss…
