What is integrated learning, in a word, heads the top of Zhuge Liang. In the performance of classification, multiple weak classifier combinations become strong classifiers.
In a word, it is assumed that there are some differences between the weak classifiers (such as different algorithms, or different parameters of the same algorithm), which results in different classification decision boundaries, which me

Let's look at the example of predicting house price. We will first perform linear regression on the data, that is, the first graph on the left. If we do this, we can obtain such a straight line that fits the data, but in fact this is not a good model. Let's look at the data. Obviously, as the area of the house increases, the changes in the housing price tend to be stable, or the more you move to the right

Ah, throw them to the model, and then let the model to train to find good features", the idea that too young too naïve. Model training is just a tool, it is not Aladdin's lamp, can give you all the help, it is not a cow, you give it grass, it gives you milk. You need to give the model a high quality input, it can return you a perfect result.
