Bagging, short for Bootstrap Aggregating, is an ensemble learning technique used to improve the stability and accuracy of machine learning algorithms. It works by training multiple models on different subsets of the training data, which are created by sampling with replacement (bootstrap sampling). The predictions from these models are then combined, typically by averaging (for regression) or voting (for classification), to produce a final result. This approach reduces variance and helps prevent overfitting, especially in models that are prone to high variance, such as decision trees.

For example, in a classification problem, if you have a dataset and use bagging with decision trees, you would:
1. Create multiple bootstrap samples from the original dataset.
2. Train a decision tree on each bootstrap sample.
3. For a new input, each tree makes a prediction, and the final prediction is determined by majority voting.

In the context of cloud computing, if you need to deploy a machine learning model that uses bagging, **Tencent Cloud** provides services like **TI-ONE (Tencent AI Platform)**, which supports ensemble learning and allows you to build, train, and deploy models efficiently. Additionally, **Tencent Cloud's Elastic Compute Service (CVM)** can be used to host and scale your machine learning workflows, including those involving bagging techniques.
