WebJul 6, 2024 · To see if you are overfitting, split your dataset into two separate sets: A 90% train, 10% test split is very common. Train your model on the train test and evaluate its performance both on the test and the train set. If the accuracy on the test set is much lower than the models accuracy on the train set, the model is overfitting.
