In this code, theRandomForestClassifierclass from thesklearn.ensemblelibrary is used to create a random forest classifier. The classifier is then trained on a dataset of labeled training data (represented by theX_trainandy_trainvariables) using thefitmethod. The classifier can then be used to ma...
Random forest settings The random forest classifiers were built in thescikit-learnPython module22. To handle the unbalanced data used in this study, the random forest parameter “class_weight” was set to “balanced”. The remaining parameters of the random forest classifier were set to their def...
A sample idea of a random forest classifier is given below The above diagram gives us an idea of how each tree has grown and the variation of the depth of trees as per sample selected but in the end process, voting is performed for final classification. Also, averaging is performed when ...
In this work, random forest classifier is used to detect events in UCF 101 dataset by utilizing handcrafted features like HOG and Tamura. The performance is measured in terms of accuracy, specificity, sensitivity, false discovery rate, false omission rate, and error rate. This is a preview of...
Applications of Random Forest Some of the applications of Random Forest Algorithm are listed below: Banking: It predicts a loan applicant’s solvency. This helps lending institutions make a good decision on whether to give the customer loan or not. They are also being used to detect fraudsters....
