WebMar 13, 2024 · Key Takeaways. A decision tree is more simple and interpretable but prone to overfitting, but a random forest is complex and prevents the risk of overfitting. Random forest is a more robust and generalized performance on new data, widely used in various domains such as finance, healthcare, and deep learning. WebI know that if I plot the random forest using the plot () command, I should get back a graph with number of trees on the x-axis, and estimated error rate on the y-axis, but when I actually plot it, I get multiple curves, all of them start quite high, as expected and drop as the number of trees increase.
