1. Clone this repository
2. Create a /data folder and put all image.txt files in the folder
3. The utils.R in the /code folder contains all functions we used to perform model fitting, including the CVgeneric function that is required in 2d).
4. In the /analysis folder:

• data_preparation.Rmd and data_preparation_v2.Rmd contains code that preprocesses the image data
• models_analysis.Rmd contains code that fits models(logistic, LDA, QDA) and further model diagnostic
• KNN_analysis.Rmd contains code that fits KNN models
• QDA_diagonstic.Rmdcontains code that analysis the QDA model and adding new features by Using EM algorithm
