Random Forest
Random Forest is a popular method used in artificial intelligence for making predictions and sorting data. Think of it like having a large group of expert advisors (decision trees) who each make their own prediction, and then vote on the final answer. It's widely used because it's reliable, easy to understand, and works well for many different types of problems. Companies use Random Forest for tasks like predicting customer behavior, detecting fraud, or recommending products. It's similar to other methods like XGBoost or Decision Trees, but is known for being more stable and less likely to make mistakes. When you see this on a resume, it indicates the candidate has experience with practical machine learning applications.
