Nonlinear Gaussian process tomography with imposed non-negativity constraints on physical quantities for plasma diagnostics
We propose a novel tomographic method, nonlinear Gaussian process tomography (nonlinear GPT), that uses the Laplace approximation to impose constraints on non-negative physical quantities, such as the emissivity in plasma optical diagnostics. While positive-valued posteriors have previously been int...
