What is Ensemble Learning?

Ensemble learning is a machine learning technique that creates a model made up of multiple learning algorithms. The model is created by combining the outputs of these algorithms and averaging them to get the final prediction.

With ensemble learning, a single machine can be trained on many models, each with different strengths and weaknesses. This technique helps to reduce the error rate in predictions.

It is used to combine the predictions of a number of models in order to improve the accuracy of the predictions. The use cases for Ensemble Learning include:

Classification problems

Ensemble Learning is a decision-making approach used to classify data into one of two or more possible classes. It is often used for classification and regression tasks, but can also be applied to clustering, feature selection, dimensional reduction and other tasks The algorithms in an ensemble are independent models. They are diverse in their approaches, assumptions and methodologies. The combination of these diverse approaches can lead to better predictive models.

Regression problems

A large suite of algorithms exist for regression problems. The most common is linear regression, however, a few more advanced algorithms exist. One such algorithm is ensemble learning, which is a form of machine learning that improves predictions by combining many weak models based on the same input variables.

Unsupervised learning problems

Ensemble Learning can be used when there is no labeled data available and we need to learn from unlabeled data. In this type of situation, ensemble learning is the best option. This method can use a combination of different machine learning algorithms to create highly accurate models. However, the results are not always 100% accurate and it can be difficult to choose which algorithm will work best for your data set.
