Ensemble Learning is using multiple learning algorithms at a time, to obtain predictions with an aim to have better predictions than the individual models.

Ensemble learning is a very popular method to improve the accuracy of a machine learning model.
It avoid overfitting and gives us a much better model.
bootstrap aggregating (Bagging) and boosting are popular ensemble methods.

In the next tutorial we will implement some ensemble models in scikit learn.

  1. i'm waiting for interview questions video and aswell please make video on Tensorflow and how to launch and use tensorboard.
    i stuck in using tensorboard graphs and how to make use of it in nlp. thank u so much for efforts.

  2. This was good video. Could you please make a video on how to implement stacking of 2 to 3 algorithms in R or Python? I would highly appreciate it. Please.

  3. i think sample size of each bag should be same as train data i.e. size-N….where N= test data…size=complete data….train data=size-N……….and u mentioned size-M<N…

  4. You have explained the concept in very easy way.
    Thanks a lot.

    Small query: In Bagging do we take data into the bags with replacement or not?

  5. Hey Shreyans! Awesome Detailed Explanation. Can we please have a link to slides in the video so that in case of revision we can go through this quickly?
