Number of folds for functions that run n-fold cross-validation.
Argument and Default Value¶
Argument is integer representing number of folds. Default number of folds is 5.
The original sample is randomly partitioned into n subsamples, n-1 of which are used for training. This is repeated n times. The n trained models are then combined into a single model.
# Runs 10:doc:`fwflag_fold` cross validation on predicting the users' genders from 1grams. # This essentially will tell you how well your model & features do at predicting gender. # Splits the data in 10 chunks, for each chunk training a model on the remaining 9 chunks. dlatkInterface.py -d fb20 -t messages_en -c user_id -f 'feat$1gram$messages_en$user_id$16to16$0_01' --outcome_table masterstats_andy_r10k --outcomes gender --combo_test_classifiers --model linear-svc --folds 10
