Random Forest Algorithm
Random Forest Algorithm combines the power of multiple decision trees to create robust and accurate predictive models. It works on the principle of group learning, where multiple individual decision trees are built independently in which each is trained on a random subset of data reduces ting and increases the generalizability of the model. When a prediction is needed, each tree in the forest gives its vote, and the algorithm combines these votes together by aggregation to give the final prediction. This tree-based approach not only improves the prediction accuracy but also increases the algorithm’s ability to detect noisy data and outliers.
Working of Random Forest Algorithm
- Random Subset: To keep things interesting, each tree in the forest is trained on a different random subset of the data. Each team member seems to get a unique view of part of the overall picture.
- Random Selection: As the team members have different skills, each pole focuses on specific areas during training. This random feature selection adds another layer of diversity to the group, so that they don’t all see the data the same way.
- Majority Voting: When it’s time to predict, each tree votes based on their own logic. It’s like taking a vote from each team member on what they think the outcome should be.
- Majority Rule: The algorithm does not rely solely on single tree views. Instead, it considers the collective intelligence of the entire forest. The final decision is based on a majority vote, allowing for stronger and more reliable predictions.
Tree Based Machine Learning Algorithms
Tree-based algorithms are a fundamental component of machine learning, offering intuitive decision-making processes akin to human reasoning. These algorithms construct decision trees, where each branch represents a decision based on features, ultimately leading to a prediction or classification. By recursively partitioning the feature space, tree-based algorithms provide transparent and interpretable models, making them widely utilized in various applications. In this article, we going to learn the fundamentals of tree based algorithms.
