Ensemble Learning
Ensemble learning is a simple and effective technique for building a strong predictive model by combining the outputs of multiple, often weaker, individual models. This method aggregates the predictions from these constituent models to achieve a more robust and superior performance than any single model could attain on its own.

Aggregation Methods in Ensemble Learning
A machine learning team has developed a single, complex predictive model. While it performs well on average, it is highly sensitive to specific, unusual data points, leading to occasional, significant errors. The team has already spent considerable time tuning this model and has seen diminishing returns on their efforts. Which of the following strategies represents the most promising approach to create a more reliable and consistently accurate system?

Cascading Models at Inference Time
An engineer is building a system to classify customer feedback. They have three different models, each with varying performance on a test dataset: Model X has 85% accuracy, Model Y has 83% accuracy, and Model Z has 86% accuracy. The engineer combines these three models into an ensemble, where the final classification is determined by a majority vote of the individual models' predictions. Assuming the models tend to make errors on different, non-overlapping examples, what is the most likely outcome for the ensemble's performance?
