Graph of different loss functions. As with the line intensities, errors are in decimal log scale. An error of 30 thus corresponds to a factor of 10³⁰ between predicted and true intensities. Since some line intensities range from 10⁻⁵⁰ to 10^—2, this kind of very high error can occur, especially early in the training phase.
