Graphs of loss function. It illustrates the training and validation loss curves for YOLOv8 and RetinaNet models on the employed dataset. The x-axis represents the number of epochs during the training process. The y-axis represents the value of the loss function. The goal during training is to minimize this value, as a lower loss indicates better alignment between the model’s predictions and the actual data.
