Ensemble Machine Learning Techniques 2.2: Ensemble Learning for Classification

The video introduces simple ensemble techniques for classification, focusing on majority voting. Majority voting is likened to democracy, where the final prediction is based on the majority of model predictions. An example of deciding to watch a movie based on friends' opinions illustrates this concept. The video discusses the advantage of ensemble learning, showing that increasing the number of models can improve overall accuracy if individual model accuracy is above 0.5. Other techniques like weighted voting and singular value decomposition are briefly mentioned. The video concludes with a promise to implement ensemble learning in the next video.
