Machine learning: ensembling and using prediction models with Caret and Shiny

For those wanting to take a step further in the machine learning world, here is the moment! Now that you are familiar with machine learning techniques, let's put several elements together and put those models in real-life use. Ensemble methods have been developed to address those very complex relationships between predictors and response variables in the presence of several candidate models. Therefore, there is no need to decide for a unique final model if you can combine them all to make more accurate predictions!. Besides this, it is also time to put those prediction models into actual action for users.

In this workshop, you will learn about ensemble methods such as voting, bagging, boosting and stacking. You will also be shown how to actually put these models into a shiny app for future use. Having a set of candidate models and an ensemble strategy, you will then get the challenge of training your own models and make a basic shiny app for the use of them.
This workshop is brought to you by Valeria Fonseca Diaz, who is currently pursuing a PhD at KU Leuven in Belgium focusing on prediction models for quality control processes in the Agrofood industry.
