Weighted Average Ensemble without Training Labels

It provides ensemble capabilities to supervised and unsupervised learning models predictions without using training labels. It decides the relative weights of the different models predictions by using best models predictions as response variable and rest of the mo. User can decide the best model, therefore, It provides freedom to user to ensemble models based on their design solutions.


nonet is a unified solution for weighted average ensemble in supervised and unsupervised learning environment. It is a novel approach to provide weighted average ensembled predictions without using labels from outcome or response variable for weight computation. In a nutshell, nonet can be used in two scenarios:

  • This approach can be used in the unsupervised environment where outcome labels not available.
  • This approach can be used to impute the missing values in the real-time scenarios in supervised and unsupervised environment because nonet does not require training labels to compute the weights for ensemble.

Getting Started:

one of the best way to start with this project is, have a look at vignettes. Vignettes provides clear idea about how nonet can contribute to ensemble different models all together.
