WebSep 2, 2024 · To achieve this, LGBM provides early_stopping_rounds parameter inside the fit function. For example, setting it to 100 means we stop the training if the predictions have not improved for the last 100 rounds. Before looking at a code example, we should learn a couple of concepts connected to early stopping.
