Yuexiang Y. - "A Random Forest works by building an ensemble of decision trees, each trained on a slightly different version of the data. The key mechanism is bagging: for each tree, we sample the training data with replacement (bootstrapping), so every tree sees a different subset of examples. On top of that, at each split the algorithm randomly selects a subset of features, so trees explore different predictors. These two sources of randomness decorrelate the trees. When we aggregate them — by averag"See full answer

Anushka R. - "One key thing I learned that made everything easier for me as a data analyst was the importance of structured thinking and communication before diving into the data. Early in my career, I used to jump directly into tasks like data cleaning, ETL processes—without fully understanding the problem or defining the questions I was trying to answer.
