Overfitting in machine learning occurs when a model becomes too tailored to noise in the dataset, reducing its generalization capability. This leads to poor performance on unseen data. Traditional solutions like early stopping help but can limit model potential. A 2019 paper from Harvard suggests that for certain tasks, overfitting could be mitigated by training models for extended iterations, observing a "double descent" in test error. This approach can outperform perpetual fine-tuning but demands significant computational resources.

Practical applications using models like neural networks reveal inconsistencies, emphasizing the importance of parameter selection. Advancements in structured exploration of algorithmic landscapes can optimize these efforts.
