What is Underfitting?

Underfitting happens when a machine learning model is too simple and fails to detect the main patterns in the data. This occurs when the model lacks enough complexity or the training data does not well represent the overall population. Underfitting results in bad performance on both the training and testing datasets. According to Ng (2015), underfitting can be spotted when both training and validation errors are high and alike.

Why is Underfitting Important?

Performance Optimization: Knowing and tackling underfitting is key for boosting the performance of machine learning models. It ensures the model learns needed patterns without being too simple.

Model Selection: This stresses the necessity to pick a suitable model and tune its settings to match the complexity of the data well.

Data Utilization: Handling underfitting makes sure that the available data is used well improving the model's ability to predict.

What are the Solutions to Underfitting?

• Increase Model Complexity: Use a harder model or include additional features to understand the underlying patterns in the data.
• Longer Training Time: Let the model train for more time or use smarter training algorithms.
• Feature Engineering: Make new features from the current ones to give the model more information.
• Reduce Regularization: If regularization techniques such as L1 or L2 are too tough, they can be eased to help the model fit the data well.
