Bias Variance Tradeoff What is Bias and Variance

WebWhile decision trees can exhibit high variance or high bias, it’s worth noting that it is not the only modeling technique that leverages ensemble learning to find the “sweet spot” within the bias-variance tradeoff. Bagging vs. boosting . Bagging and boosting are two main types of ensemble learning methods. WebMay 5, 2024 · Variance occurs when the model is highly sensitive to the changes in the independent variables (features). The model tries to pick every detail about the relationship between features and target. It even learns the noise in the data which might randomly occur.
