What is ensemble learning in the context of classification?Extracting features from unstructured dataFiltering noisy data from the datasetCombining multiple classifiers to improve performanceVisualizing high-dimensional data

State True or False:Ensemble learning is based on the idea that the probability of the majority of classifiers making a mistake is higher than the probability of any one of them making a mistake.

Supervised Learning Algorithms:3. Ensembling:o Combines the predictions of multiple machine learning models thatare individually weak to produce a more accurate prediction on a newsample.o Examples of ensemble techniques:• Bagging with Random Forests,• Boosting with XGBoost143. Ensembling:14监督学习算法:o结合个别弱的多个机器学习模型的预测，以对新样本产生更准确的预测。o集成技术的例子:•用随机森林装袋,•使用XGBoost提升

Which ensemble learning technique focuses on reducing bias?Review LaterBaggingBoostingBoth bagging and boosting equally focus on reducing bias.Neither bagging nor boosting focuses on reducing bias.
