Someone mind helping me understand what these "loss" logs mean for the accuracy/quality of the model? It's the output from a radtts model training. As in, which of these do I care about? Do these numbers indicate a bad/good model?

iteration: 464  (3.30 s)  |  lr: 0.001  |  loss_mel: -1.067  |  loss_prior_mel: 0.517  |  loss_ctc: 3.740  |  loss_duration: 0.286  |  loss_f0: 0.005  |  loss_energy: 0.005  |  loss_vpred: 1.372  |  binarization_loss: 0.791
