Multi-fidelity information fusion. (IMAGE)
Caption
Theoretical and simulation estimates of turbulent transport (high-dimensional data that depend on plasma conditions such as density, temperature, and magnetic field) are used as low-fidelity data, and experimentally observed plasma confinement performance data are used as high-fidelity data. By incorporating correlations between low and high-fidelity data, multi-fidelity modeling compensates for the lack of high-fidelity data and enhances predictive accuracy of the plasma confinement performance.
