TODO: make sure the right getRelated function is called (with itemID)
* Bottleneck appears to be at ALUserBasedRecommender.doEstimatePreference
SETTINGS
new user has from 1 - 10 items
AL item is selected for evaluation and added to the user's items
Estimate the ratings of witheld items of a user (on avg less than 100)
OPTIMIZATIONS
User Neighborhood construction:
1) select users that have rated the item for which rating needs to be estimated
2) user must have rated at least on of the items that AL_user has rated
Currently it appears that correlation is calculated for all of the users which is unecessary.
From Log 2 we can see that construction of user neighborhood took ~60s, and preference estimation took ~60S
--------------------------------
User Neighborhoud
1) pick only users that have correlation != 0 (have some overlapping items with AL_user)
Modified
ALUserNeighborhood.Retriever.getValue(final Object userId)
Added:
H2JDBCDataModel.getRelatedUsers(User user)
RESULTS:
x60 improvement: before it took 60s; now 1s
Preference Estimation still takes long time
------------------------------------
Preference estimation
1) Need only users that have rated the item for which want to obtain estimates for a current user; and are related to the current user
Query Optimization
H2JDBCDataModel
public Collection<User> getRelatedUsers(User theUser, Object itemID) throws TasteException {

Neighborhood construction improved from taking 25% -> 5%
Now need to improve doEstimate
