Table 2 Comparison of ensemble methods.

From: Boosting skin cancer diagnosis accuracy with ensemble approach

Method

Strengths

Weaknesses

Max Voting

Simple, leverages diversity

Ignores model performance

Bagging

Reduces variance, stabilizes models

Requires large datasets, does not reduce bias

Boosting

Reduces bias, improves accuracy on hard cases

Computationally costly, sensitive to noise

Stacking

Allows complex combinations

Requires tuning, risk of overfitting
