This term appears frequently in the method-related threads.
Is blending a specific method in data-mining and statistical learning? I cannot get a relevant result from google.
It seems blending is mixing up outcomes from many models and resulting in a better result. Is there any resource that helps me knowing more about it?
Some papers to help you further understand what blending is. I think you can also google for ensemble selection/learning, and stacking as well.
Your general understanding of ‘mixing up outcomes from many models and resulting in a better result’ is correct though.
