Data Mining Project 2

• data_preprocessing: load the data from txt file, use one-hot encoding to deal with string feature and normalize continuous value.

• cross_vali: do 10 fold cross validation and print out accuracy, precision, recall, f1

• knn/naive_bayes/svm/decision_tree/decision_tree_boosted/random_forest: classifiers, run by command line "python xxx.py" and get 10-fold cross validation result of each dataset
