Comparison between the node values inferred by a standard, maximum likelihood-based, inversion code, and the results of the convolutional neural network, using set 2 as the training set. First two rows: spatial parameter distributions. Third row: scatter plot between the two. From top to bottom: temperature at log τ = −0.8 and log τ = 0; line-of-sight velocity at log τ = −0.5; line-of-sight magnetic field at log τ = −1.5 and log τ = 0.3. Units are kK, km/s, and gauss, for temperature, velocity, and magnetic field, respectively.
