A mini ML competition. Who can produce the best model to predict pass/fail

• Download the Open University Learning Analytics dataset from here
• Import the studentVle.csv, studentAssessment.csv and studentInfo.csv files into R

• Calculate the average daily number of clicks (site interactions) for each student from the studentVle dataset
• Calculate the average assessment score for each student from the studentAssessment dataset
• Merge your click and assessment score average values into the the studentInfo dataset

• Split your data into two new datasets, TRAINING and TEST, by randomly selecting 20% of the students for the TEST set

• Generate summary statistics for the variable final_result
• Ensure that the final_result variable is binary (Remove all students who withdrew from a courses and convert all students who recieved distinctions to pass)
• Visualize the distributions of each of the variables for insight
• Visualize relationships between variables for insight

• You will be allocated one of the following models to test:

  CART, Neural Network, Genetic Algorithm, Naive Bayes, K-nearest neighbors

• Using the trainControl command in the caret package create a 10-fold cross-validation harness:
  control <- trainControl(method="cv", number=10)

• Using the standard caret syntax fit your model and measure accuracy:
  fit <- train(final_result~., data=TRAINING, method=YOUR MODEL, metric="accuracy", trControl=control)

• Generate a summary of your results and create a visualization of the accuracy scores for your ten trials

• Make any tweaks to your model to try to improve its performance

• Use the predict function to test your model
  predictions <- predict(fit, TEST)
• Generate a confusion matrix for your model test
  confusionMatrix(predictions, TEST$final_result)
