Taste Recommender AL Speed Optimization

Tue, 03/25/2008 - 21:25 — admin

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 {

    /**
     * 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
     *
     * In some of the models it appears that correlation is calculated for all
     * of the users which is unnecessary. pick only users that have correlation !=
     * 0 (have some overlapping items with AL_user)
     *
     *
     * NOTE: This is a hacky implementation and probably needs to be changed in
     * the future
     *
     * Return users that have correlation != 0 to the current user this means
     * that they must have rated at least one of the items in common with the
     * user
     *
     * e.g. SELECT DISTINCT user_id FROM taste_preferences where item_id=376 and
     * user_id in ( SELECT user_id FROM taste_preferences where (item_id=242 or
     * item_id=393) )
     *
     *
     * Query Optimization:
     *
     * Restricted by @param itemID
     *
     * GOOD: SELECT DISTINCT user_id FROM taste_preferences where item_id=376
     * and user_id in ( SELECT user_id FROM taste_preferences
     * where (item_id=242 or item_id=393) )
     * 0.8 sec
     * 
     * AVOID:
     * SELECT DISTINCT user_id FROM taste_preferences
     * where user_id in ( SELECT user_id FROM taste_preferences
     * where (item_id=242 or item_id=393) )
     * 7 sec
     *
     *
     *
     * NOT Restricted by @param itemID
     *
     * GOOD: SELECT DISTINCT user_id from taste_preferences 
     * where (item_id=242 or item_id=393)
     * 0.06 sec
     *
     * AVOID:
     * SELECT DISTINCT user_id FROM taste_preferences where user_id in (
     * SELECT user_id FROM taste_preferences where (item_id=242 or item_id=393) )
     * and item_id=376
     * 7 sec
     *

     *
     *
     *
     *
     * @param theUser
     * @param itemID
     * @return

Profile

Neighborhood construction improved from taking 25% -> 5%

 

Now need to improve doEstimate
