TL;DRRandom forests average many decision trees to cut overfitting and boost accuracy.
A random forest trains many trees on random subsets of data and features, then averages (or votes) their predictions. This bagging averages away individual trees' overfitting, giving a robust, accurate model that needs little tuning. You lose the single readable tree, but gain stability and feature-importance estimates. A reliable go-to for tabular data.
Key points
Many trees on random data/feature subsets
Average/vote → reduces overfitting (bagging)
Robust, accurate, little tuning
Loses single-tree interpretability
Common mistakes
Expecting one readable rule set
Assuming it beats gradient boosting always
Ignoring it as a strong tabular baseline
