Algorithms in Machine Learning (1) - Random Forest and GBDT Based on Decision Tree Model Combination

Algorithms in Machine Learning (1) - Random Forest and GBDT Based on Decision Tree Model Combination. Decision Tree This algorithm has many good features, such as training time complexity is low, the prediction process is relatively fast, the model is easy to display (easy to get the decision tree made of pictures) and so on. But at the same time, the single decision tree has some bad points, such as easy over-fitting, although there are some ways, such as pruning can reduce this situation, but not enough. Model combinations (say Boosting, Bagging, etc.) are related to decision trees ...

How to choose the most suitable machine learning algorithm for your regression problem

The performance of different machine learning algorithms depends on the size and structure of the data. Therefore, unless we use traditional trial and error experiments, we have no clear way to prove that a choice is right.

Machine learning or artificial intelligence

The most important algorithm is the neural network, which is not very successful due to overfitting (the model is too powerful, but the data is insufficient). Still, in some more specific tasks, the idea of using data to adapt to functionality has achieved significant success, and this also forms the basis of today's machine learning.
