Combining models

There are several ways in which models can be combined. We are going to look at each method in this section.

Combining by voting

Let's use an example to understand this method of combining models.

Consider that we have run three models and created a table like this:

We have the confidence for each model and its prediction. Let's see how we can combine these models.

If we take a look at the first row, we can see that each of these models is predicting that a person is going to leave. Hence, if we combine the predictions, we are still predicting that the person is going to leave. The confidence value, or the final confidence, is acquired by adding up the confidence values of all the models and dividing...
