Why can’t we use gradient descent for random forest? To do gradient descent, you need continuous parameters, and the loss function has to be differentiable with respect to them. Random forests have discrete hyperparameters (e.g. tree depth, number of trees, number of features, etc.). So, unfortunately, gradient descent won’t work in this context.
Why is GBM better than random forest? If you carefully tune parameters, gradient boosting can result in better performance than random forests. However, gradient boosting may not be a good choice if you have a lot of noise, as it can result in overfitting. They also tend to be harder to tune than random forests.
In which case the gradient descent algorithm works best? Gradient descent is best used when the parameters cannot be calculated analytically (e.g. using linear algebra) and must be searched for by an optimization algorithm.
