The difference is that the Decision Tree is biased, but the Random Forest is not. If you test this Random Forest classifier on multiple sets of new test data, you will find that it will do better than the Decision Tree classifier. Conclusion WebMar 22, 2024 · 21. You are getting 100% accuracy because you are using a part of training data for testing. At the time of training, decision tree gained the knowledge about that data, and now if you give same data to predict it will give exactly same value. That's why decision tree producing correct results every time. WebDecision Trees are a non-parametric supervised learning method used for both classification and regression tasks. The goal is to create a model that predicts the value of a target variable by learning simple decision rules inferred from the data features. The decision rules are generally in form of if-then-else statements. dog wash lincoln city or
