Detailed Description

Cross-validation for rating prediction.

Member Function Documentation

static RatingPredictionEvaluationResults DoCrossValidation	(	this RatingPredictor	recommender,
		uint	num_folds = `5`,
		bool	compute_fit = `false`,
		bool	show_fold_results = `false`
	)		`[inline, static]`

Evaluate on the folds of a dataset split.

Parameters:

recommender	a rating predictor
num_folds	the number of folds
compute_fit	if set to true measure fit on the training data as well
show_fold_results	if set to true to print per-fold results to STDERR

Returns:: a dictionary containing the average results over the different folds of the split

static RatingPredictionEvaluationResults DoCrossValidation	(	this RatingPredictor	recommender,
		ISplit< IRatings >	split,
		bool	compute_fit = `false`,
		bool	show_fold_results = `false`
	)		`[inline, static]`

Evaluate on the folds of a dataset split.

Parameters:

recommender	a rating predictor
split	a rating dataset split
compute_fit	if set to true measure fit on the training data as well
show_fold_results	set to true to print per-fold results to STDERR

Returns:: a dictionary containing the average results over the different folds of the split

static void DoIterativeCrossValidation	(	this RatingPredictor	recommender,
		uint	num_folds,
		uint	max_iter,
		uint	find_iter = `1`,
		bool	show_fold_results = `false`
	)		`[inline, static]`

Evaluate an iterative recommender on the folds of a dataset split, display results on STDOUT.

Parameters:

recommender	a rating predictor
num_folds	the number of folds
max_iter	the maximum number of iterations
find_iter	the report interval
show_fold_results	if set to true to print per-fold results to STDERR

static void DoIterativeCrossValidation	(	this RatingPredictor	recommender,
		ISplit< IRatings >	split,
		uint	max_iter,
		uint	find_iter = `1`,
		bool	show_fold_results = `false`
	)		`[inline, static]`

Evaluate an iterative recommender on the folds of a dataset split, display results on STDOUT.

Parameters:

recommender	a rating predictor
split	a rating dataset split
max_iter	the maximum number of iterations
find_iter	the report interval
show_fold_results	if set to true to print per-fold results to STDERR
