  "title": "Privacy-preserving federated tensor decomposition of single-cell immune data: recovering multicellular programs across institutions",
  "summary": "Tensor decomposition of donor $\\times$ cell-type $\\times$ gene single-cell data recovers \\emph{multicellular programs}: coordinated axes of inter-individual transcriptional variation that span cell types and stratify disease. Yet immune single-cell atlases are increasingly multi-institution, multi-ancestry, and governed, so patient cells often cannot be pooled. We present a federated estimator: each site computes a local program subspace, and a coordinator merges these by stacked SVD under feder",
