Detailed Description

Class that contains static methods for item prediction.

Member Function Documentation

static void WritePredictions	(	this IRecommender	recommender,
		IPosOnlyFeedback	train,
		System.Collections.Generic.IList< int >	candidate_items,
		int	num_predictions,
		string	filename,
		System.Collections.Generic.IList< int >	users = `null`,
		IEntityMapping	user_mapping = `null`,
		IEntityMapping	item_mapping = `null`
	)		`[inline, static]`

Write item predictions (scores) to a file.

Parameters:

recommender	the IRecommender to use for making the predictions
train	a user-wise IPosOnlyFeedback containing the items already observed
candidate_items	list of candidate items
num_predictions	number of items to return per user, -1 if there should be no limit
filename	the name of the file to write to
users	a list of users to make recommendations for
user_mapping	an IEntityMapping object for the user IDs
item_mapping	an IEntityMapping object for the item IDs

static void WritePredictions	(	this IRecommender	recommender,
		IPosOnlyFeedback	train,
		System.Collections.Generic.IList< int >	candidate_items,
		int	num_predictions,
		TextWriter	writer,
		System.Collections.Generic.IList< int >	users = `null`,
		IEntityMapping	user_mapping = `null`,
		IEntityMapping	item_mapping = `null`
	)		`[inline, static]`

Write item predictions (scores) to a TextWriter object.

Parameters:

recommender	the IRecommender to use for making the predictions
train	a user-wise IPosOnlyFeedback containing the items already observed
candidate_items	list of candidate items
num_predictions	number of items to return per user, -1 if there should be no limit
writer	the TextWriter to write to
users	a list of users to make recommendations for; if null, all users in train will be provided with recommendations
user_mapping	an IEntityMapping object for the user IDs
item_mapping	an IEntityMapping object for the item IDs

static void WritePredictions	(	this IRecommender	recommender,
		int	user_id,
		System.Collections.Generic.IList< int >	candidate_items,
		System.Collections.Generic.ICollection< int >	ignore_items,
		int	num_predictions,
		TextWriter	writer,
		IEntityMapping	user_mapping,
		IEntityMapping	item_mapping
	)		`[inline, static]`

Write item predictions (scores) to a TextWriter object.

Parameters:

recommender	the IRecommender to use for making the predictions
user_id	ID of the user to make recommendations for
candidate_items	list of candidate items
ignore_items	list of items for which no predictions should be made
num_predictions	the number of items to return per user, -1 if there should be no limit
writer	the TextWriter to write to
user_mapping	an IEntityMapping object for the user IDs
item_mapping	an IEntityMapping object for the item IDs
