WebLSTMs are stochastic, meaning that you will get a different diagnostic plot each run. It can be useful to repeat the diagnostic run multiple times (e.g. 5, 10, or 30). The train and validation traces from each run can then be plotted to give a more robust idea of the behavior of the model over time. WebDec 13, 2024 · So there is not enough time to adapt the weights for overfitting here. So to get the result of overfitting you want to have the same data multiple times inside your training dataset so the weights can change enought to overfitt because you only change them just one small step per epoch.
