rational for picking loss function #19

Is there some reasoning you can share about why you used a different loss function for each type of noise generation? gaussian : mse text : mae impulse random : L0

Please refer to the original paper. Theoretically these noise and loss pairs are optimal. (mean, median, or mode of noisy images is a clean image if a noise is Gaussian, text, or impulse noise respectively)
