An introduction to random forest model algorithm and how to apply random forest classification algorithm using data for a case study in predictive analysis.
"Random Forest", "AdaBoost", "Naive Bayes", "LDA", "QDA"] classifiers = [ KNeighborsClassifier(3), SVC(kernel="linear", C=0.025), SVC(gamma=2, C=1), DecisionTreeClassifier(max_depth=5), RandomForestClassifier(max_depth=5, n_estimators=10, max_features=1), AdaBoostClassifier(), ...
Random Forest is one of the widely used tree-based ensemble classification algorithms. Many aspects of building tree ensembles are introduced to reduce correlation among decision trees within the forest. Bootstrap is used in Random Forest to reduce bias decision tree and to decide splits in every...
Random Forests Algorithms are not ideal in the following situations: Extrapolation: Random Forest regression is not ideal in the extrapolation of data. Unlike linear regression, which uses existing observations to estimate values beyond the observation range. ...

Random Forest works well when we are trying to avoid overfitting from building a decision tree. Also, it works fine when the data mostly contain categorical variables. Other algorithms like logistic regression can outperform when it comes to numeric variables but when it comes to making a decision...
