The bias-variance trade-off is the tension between bias and variance in ML models. Biased models fail to capture the true trend, resulting in underfitting, whereas low-bias high-variance models likely result in overfitting.

A fundamental concept in machine learning is the bias-variance tradeoff, which entails striking the ideal balance between model complexity and generalization performance. It is essential for figuring out which model works best for a certain situation and for comprehending how several models function.

The Bias Variance Trade-off. Repeating this aggregation across our range of model complexities, we can see the relationship between bias and variance in prediction errors manifests itself as a U-shaped curve detailing the trade off between bias and variance.

In machine learning, the bias-variance trade-off is a fundamental concept affecting the performance of any predictive model. It refers to the delicate balance between bias error and variance error of a model, as it is impossible to simultaneously minimize both. Striking the right balance is crucial for achieving optimal model performance.

The bias-variance tradeoff refers to the tradeoff that takes place when we choose to lower bias which typically increases variance, or lower variance which typically increases bias. The following chart offers a way to visualize this tradeoff: The total error decreases as the complexity of a model increases but only up to a certain point.
