WebOverfitting a model is more common than underfitting one, and underfitting typically occurs in an effort to avoid overfitting through a process called “early stopping.” If undertraining or lack of complexity results in underfitting, then a logical prevention strategy would be to increase the duration of training or add more relevant inputs. Web6 de dez. de 2024 · In this article, I will present five techniques to prevent overfitting while training neural networks. 1. Simplifying The Model. The first step when dealing with overfitting is to decrease the complexity of the model.
