6. Simulation-based inference (cont'd)

  1. Run a lot of simulations
  2. Use simulation results to train a neural network
  3. Make clinical measurements
  4. Ask neural network what model parameters would match measurements
  5. Use parameter values to make diagnosis

Running the simulations is computationally expensive.
