I have to build a hybrid model for prediction of heart disease. Before that, i want everyone of you to clarify me few things.

[1] Is it possible to pass output of 1 classifier to other classifier? like SVM-> ANN -> RF -> LR

- According to me, it is possible but label/target data will be reduce when passed from 1 classifier to other classifier. In other classifier, we have to give same size of training data, so that size of data will be matched. But that a trick.

- suggest me some paper/code, if you have anything like that.

[2] What are parameter should i consider while building Hybrid model?

- i am aware of Kappa value but suggest me more

[3] On what basis should i select algorithms for Hybrid Model?

[4] What are right practices or common methods for building Hybrid Model?

- i know ensemble learning but suggestion are welcome.
