Web27 jul. 2016 · When I use validation_split to create a test set, The val_acc and val_loss either go inverse to the training data (e.g val_acc stays the same while val_loss goes … WebIf your training loss is much lower than validation loss then this means the network might be overfitting. Solutions to this are to decrease your network size, or to increase dropout. For example you could try dropout of 0.5 and so on. If your training/validation loss are about equal then your model is underfitting.
Web15 dec. 2024 · Plot the training and validation losses. The solid lines show the training loss, and the dashed lines show the validation loss (remember: a lower validation loss indicates a better model). While building a larger model gives it more power, if this power is not constrained somehow it can easily overfit to the training set. Web17 jul. 2024 · If your training loss is much lower than validation loss then this means the network might be overfitting . Solutions to this are to decrease your network size, or to increase dropout. For example you could try dropout of 0.5 and so on.

WebIf so, that could explain the difference since dropout is enabled during training (leading to higher losses) whereas it is not enabled during validation/test. Maybe your validset is too easier than your trainset. You can increase validation dataset size. The validation dateset is smaller, but not easier.
Web29 mrt. 2024 · When a model trains with dropout, only a percentage of the total weights (in your case 50%) are used in predictions, which tends to lower the prediction accuracy. …
Web11 aug. 2024 · When we are training the model in keras, accuracy and loss in keras model for validation data could be variating with different cases.
