A decision tree algorithm is a machine learning algorithm that uses a decision tree to make predictions. It follows a tree-like model of decisions and their possible consequences. The algorithm works by recursively splitting the data into subsets based on the most significant feature at each node of the tree. Like random forests, gradient boosted trees can't learn and reuse internal representations. Each decision tree (and each branch of each decision tree) must relearn the dataset pattern. In some datasets, notably datasets with unstructured data (for example, images, text), this causes gradient boosted trees to show poorer results than other …The biggest issue of decision trees in machine learning is overfitting, which can lead to wrong decisions. A decision tree will keep generating new nodes to fit the data. This makes it complex to interpret, and it loses its generalization capabilities. It performs well on the training data, but starts making mistakes on unseen data.
