Ricky Ho has created a reference a 6-page PDF reference card on Big Data Machine Learning, with examples implemented in the R language. (A free registration to DZone Refcardz is required to download the PDF.) The examples cover:

• Predictive modeling overview (how to set up test and training sets in R)
• Linear regression (using lm)
• Logistic regression (using glm)
• Regression with regularization (using the glmnet package)
• Neural networks (using nnet)
• Support vector machines (using tune.svm from the e1071 package)
• Naïve Bayes models (using naiveBayes from the e1071 package)
• K-nearest-neighbors classification (using the knn function from the class package)
• Decision trees (using rpart)
• Ensembles of trees (using the randomForest package)
• Gradient boosting (using the gbm package)
