WebMar 7, 2024 · A random forest is a meta-estimator (i.e. it combines the result of multiple predictions), which aggregates many decision trees with some helpful modifications: The … Web$\begingroup$ A random forest regressor is a random forest of decision trees, so you won't get one equation like you do with linear regression.Instead you will get a bunch of if, then, else logic and many final equations to turn the final leaves into numerical values. Even if you can visualize the tree and pull out all of the logic, this all seems like a big mess.
