Random Forest
Random Forest is a popular method used by data analysts and scientists to make predictions and analyze large amounts of information. 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 in business for tasks like predicting customer behavior, detecting fraud, or recommending products. Companies value this approach because it's reliable, handles complex data well, and is less likely to make mistakes compared to simpler methods. When you see this term in a resume, it typically indicates that the candidate has experience with advanced data analysis and prediction tasks.
