# Pt Train Classification Model Lr
Trains a classification model using a given dataset, optimizer, and number of epochs with learning rate decay.  

early_stopping_rounds: Specifies the number of rounds to monitor the evaluation loss when early_stopping is enabled and validation data is specified. If the loss does not decrease compared to the current best loss within this period, training will be stopped.
output_best_val_model: Whether to outputs the model with the best val loss or the model from the last epoch.
