About

A digital twin you can question before you advise.

Pratibimb (प्रतिबिम्ब, “reflection”) fuses a simulated health record with simulated wearable streams, keeps a physiological model in sync with them, and predicts adverse glucose events in advance. It is a proof of concept on synthetic data, not a medical device.

Architecture

  1. 01
    Truth simulator
    240 synthetic patients × 28 days; richer than the twin
    Synthetic data
  2. 02
    EHR + wearables
    FHIR R4 bundles; CGM, HR, HRV, steps, sleep
    Two streams
  3. 03
    Twin
    Glucose–insulin ODE + 64-member EnKF, 4-h forecasts
    Physiology
  4. 04
    Risk layer
    LightGBM on twin + CGM features, TreeSHAP drivers
    Machine learning
  5. 05
    API
    FastAPI REST + WebSocket replay; static demo export
    Python
  6. 06
    Console
    Next.js clinician console, What-If Lab
    Web

The twin never sees the simulator’s hidden labels or parameters; every metric is twin-versus-truth on held-out patients.
