Why is Random Forest algorithm popular?

Random forest is a Supervised Machine Learning Algorithm that is used widely in Classification and Regression problems. It builds decision trees on different samples and takes their majority vote for classification and average in case of regression. It performs better results for classification problems.

What is the advantage of using a Random Forest algorithm over a decision tree algorithm?

Introduction to Random Forest The biggest advantage of Random forest is that it relies on collecting various decision trees to arrive at any solution. This is an ensemble algorithm that considers the results of more than one algorithms of the same or different kind of classification.

What is Random Forest algorithm in machine learning analytics Vidhya?

Random forests are a supervised Machine learning algorithm that is widely used in regression and classification problems and produces, even without hyperparameter tuning a great result most of the time. It is perhaps the most used algorithm because of its simplicity.

Is Random Forest good for categorical data?

A random forest is an averaged aggregate of decision trees and decision trees do make use of categorical data (when doing splits on the data), thus random forests inherently handles categorical data. Yes, a random forest can handle categorical data.

How does random forest algorithm work?

Working of Random Forest Algorithm

1. Step 1 − First, start with the selection of random samples from a given dataset.
2. Step 2 − Next, this algorithm will construct a decision tree for every sample.
3. Step 3 − In this step, voting will be performed for every predicted result.

Why random forest is called Random Forest?

The most common answer I get is that the Random Forest are so called because each tree in the forest is built by randomly selecting a sample of the data.

Which is true about Random Forest algorithm?

Which of the following is/are true about Random Forest and Gradient Boosting ensemble methods? Both algorithms are design for classification as well as regression task. Random forest is based on bagging concept, that consider faction of sample and faction of feature for building the individual trees.
