Machine Learning with Tidymodels

Machine Learning with Tidymodels

Course Level: Intermediate

Machine learning is the process of applying statistical techniques to gain systematic information about a quantity of interest. We will be specifically focusing on how we can use the {tidymodels} suite of packages to implement these techniques. We cover key reasons for model fitting, such as predicition and inference, on quantitative and qualitative responses.

Course Outline

  • Introduction: A general introduction into statistical moedlling techniques and the {tidymodels} R package.
  • Quantitaive model fitting: Using {parsnip} to perform simple and multiple linear regression, allowing us to fit a model.
  • Qualitative model fitting: Using {parsnip} to perform logistic regression and fit the model.
  • Classification: Brief introduction to the K-nearest neighbours (KNN) technqiue for cases where a categoric response has more than two possible outcomes.
  • Model assessment: Testing the reliability of model predictions and finding optimum models using resampling methods like the validation set approach.
  • Model pre-processing with {recipes}: Including variable trasnformations, one-hot encoding and normalisation

Learning Outcomes

By the end of the course participants will…

  • have a thorough understanding of popular analytical techniques practised in industry today
  • be able to make model predictions in cases of a numeric or categoric response
  • assess model validity through the validation set approach
  • understand which technique applies to their own data
  • efficiently and effectively analyse their own data using said techniques in R
  • apply the developed workflow practice to other modelling techniques
  • pre-process their own data using {recipes}

Prior Knowledge

It will be assumed that participants are familiar with R. For example inputting data, basic visualisation, basic data structures and use of functions. Attending the Introduction to R course will provide a sufficient background, but the programming with R will be helpful.
