WebOverfitting is a concept in data science, which occurs when a statistical model fits exactly against its training data. When this happens, the algorithm unfortunately cannot perform accurately against unseen data, defeating its purpose. Generalization of a model to new data is ultimately what allows us to use machine learning algorithms every ... WebJun 29, 2024 · Simplifying the model: very complex models are prone to overfitting. Decrease the complexity of the model to avoid overfitting. For example, in deep neural networks, the chance of overfitting is very high when the data is not large. Therefore, decreasing the complexity of the neural networks (e.g., reducing the number of hidden …

WebThis condition is called underfitting. We can solve the problem of overfitting by: Increasing the training data by data augmentation.
