Make patient data shareable. Without sharing patient data.
The model learns from real clinical records.
Trained under differential privacy, it carries the patterns, not the people. It cannot leak any individual, so the model itself can safely leave.
The model is evaluated against real data on three pillars: statistical similarity, consistency with clinical rules and downstream utility.
Conditional ECG generators get the diagnoses right and the patients wrong. DCDM-ECG conditions a latent diffusion model on age, sex, height, weight and heart rate alongside the diagnostic labels. On PTB-XL it tracks the real age distribution, follows a specified heart rate to 2.4 bpm and reaches TSTR macro-AUROC 0.885, 4.5 points above the strongest label-only baseline.
Thirteen sampling policies for training an ECG classifier on synthetic data only. None beats a naive bootstrap of the real training distribution. Rebalancing toward rare classes multiplies generator noise instead of adding support.
→Across six tabular datasets, DP-SGD synthesis has a sharp viability boundary set by the ratio of training samples to encoded dimensions, N/d ≈ 50–300. Marginal-based DP methods can be viable two orders of magnitude lower.
→On a CITE-seq PBMC dataset, grouping single-cell features into biological modules substantially beats flat baselines at matched parameter budgets. Preliminary, one dataset.
→A reinforcement-learning gym for medical-reasoning agents, on multi-modal patient trajectories. DP-trained.
Coming soonOutputs as FHIR R4 and R5, or formats tailored for research.
Cohorts, edge cases and markets real data cannot give you. Generated on demand, PHI-free.
Plan and simulate trials before the first enrolment.
Run internal studies without the data-access wait.
Hand the same cohort to collaborators, reproducible by seed.
Build and test products against realistic data, no PHI to handle.
Privacy guarantees come from the mathematics, not from policy. The generator is built to slot into regulated healthcare workflows.
Based in Iceland, inside the EU/EEA. No real data on our production systems, and differential privacy means no individual can be recovered.
Synthetic data carries no personal data, which eases the Act's data-governance burden on the medical AI you build and test.
Synthetic data carries no PHI, with proof.
Your own cloud, with SSO, RBAC and audit logs. The data never leaves your infrastructure, and we never see it.
