As in, say the model's loss has stopped decreasing for the past 10 epochs (this number is arbitrary), you may want to stop the model training here and go with the model weights that had the lowest loss (10 epochs prior). 提前停止会在模型开始过度拟合之前停止训练。例如,假设模型的损失在...

Based on the nature of our predictions, it’s easy to see why we might need a unique loss function. Many of us have calculated losses in regression or classification settings before, but rarely, if ever, together. Obviously, our total loss must be an aggregate(集合) of losses from both ...
ifpatience = 2, then we will ignore the first 2 epochs with no improvement, and will only decrease the LR after the 3rd epoch if the loss still hasn’t improved then. Default: 10. 耐心值
Repeat step 3 to 6 until model is sufficiently trained, for example, until the loss is not decreasing for a while, or simply until you run out of money or patience. Distributed data parallel distributes a mini-batch to multiple GPUs ...

@hugowjd: Great work. My initial guess - Since there are two different image sizes which are getting loaded, the validation loss is not decreasing much. May be if you can just only with only 2024 dataset, try to see if the model performance improves. ...
