Prom dresses for cheap

    If you think about it, a prom dress is a lot like a wedding dress. With all the other items we need there should be some kind of restraint when it comes to dresses. However, in the heat of the moment we spend exorbitant amounts of money on these gowns only wear them once in our lifetime. If you are going to prom maybe you and your parents can look into alternatives for your magical, $400 fantasy gown. There is a viable alternative. Now you can find prom dresses for cheap!  One of the easiest and fastest places to search is right where you are now – on the web. Unbelievably, your dress can cost around 99 dollars which is quite reasonable to have your dream prom come true.        Shop here to find aProm Dress Cheap        

Work Log

running experiments r2

Profiling:

Interesting to notice:

Getting user's neighborhood now takes the majority of time (46%)
TODO: This could be a good spot to optimize

Suprisingly: in user correlation getNumItems takes the majority of item
TODO: Not sure why - Investigate

 

 

Profiling

Profiled getUserNeighborhood in more detail.  Vast majority of time is spent executing the query.

TODO: Improve this part

 

Enhancements

Added more properties that will be loaded from the file

 

Work Log

New Taste 1.7.2 was released.

Refactoring my source code to make integration with the base code [taste] easier.

e.g. VOIUserBasedRecommender

 

Work Log

Average MAE over 25 randomAL runs:


0.84 0.83 0.83 0.83 0.83 0.83 0.82 0.83 0.83 0.83 0.83 0.83 0.83 0.83 0.83 0.83 0.83 0.83 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82 0.82

Problem: The numbers are not decreasing much (contradictory to expectations)

ToDo: Need to find the problem - check the code

Log

It is not caused by the old bug in GenericUserBasedRecommender

Correlation

The problem might lie in the correlation function.  When using PearsonCorrelation get very bad results MAE = max; when using UnceteredPearson Correlation get much better results MAE=0.9.

There was a small bug in the code (submitted to the SourceForge).

CFAL Deployment

Deploy my software to the machines in the lab e.g. simu2

Mounted a network folder over samba (ackward, but works)
(did it through Places/Network)

Installed java /home/neil/java/...

Build jar for deployment with NetBeans

-sh-2.05b$ pwd
/home/neil/proj/CFAL/ex/rnd1
nohup nice -18 /home/neil/java/jre1.6.0_05/bin/java -Xmx1g -Xms1g -Djava.util.logging.config.file=logging.properties -jar /home/neil/proj/CFAL/dist/JavaProject1.jar program.properties &
 

dist in the same directory as experiment
nohup /home/neil/java/jre1.6.0_05/bin/java -Xmx1g -Xms1g -Djava.util.logging.config.file=logging.properties -jar ./dist/JavaProject1.jar program.properties &
 

 

To check which machines are running matlab:  /usr/local/matlab2/etc/lmstat -a

also do a top command to see if anything else is running

To see the bottom of the file as it is being written (concurrent) to use: tail -f  nohup.out

 tail nohup.out -n 1000 > data.tmp.txt

Taste Active Learning Optimization Rewrite

Started writing all of the methods from scratch optimized for active learning tasks for Taste Recommender.

Before:

INFO: It took ms: 140,568

After:

Mar 31, 2008 12:06:21 PM org.hrstc.taste.al.AL_CF evaluate
INFO: It took ms: 27,835
 

 

[MOVED] TODO

X

At each iteration calculate MAE for all of the items (pick next item randomly)

Profiling

 

X

May add enhancement that uses only top n neighbors.  Might implement by using group by and count (neighbor that has the most items in common should be seleted).

Could select best on two criterions:

1) the users have rated the most items in common

[optional]

2) the user have rated the most test items (if use this criteria for all of the methods, it is a fair one)

 

X -

unexpected results for Random (MAE does not decrease)

Double check that correlation is calculated correctly

double check MAE calculation etc.

 

 

Taste Recommender AL Speed Optimization

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 {

Optimization - doEstimate

cache correlation

calculate neighborhood and the correspondings corelations (only once per run)
hood = (user_item1 or user_item2 ...) and (test_item1 or test_item2 ...)

 

Photo Camera

This is the top choices (ordered from top down) for the midrange camera (under $300) that I bought for my father in law.

Important features:

Usable power on - so far the best one is the sliding window

Good technical specs

Reasonable cost - one of the cost factors is the cost of the memory; in this repsects SD is by far the best.  So in the begining I was searching only for cameras with SD cards; although that conflicted with my sliding window requirement, so I have added sony's memory stick.

Recommendation Discovery

I have found this very interesting aspect of recommender systems at http://www.aggregateknowledge.com/discover.html

Discover things you didn't know you where looking for.

serendipitous http://en.wikipedia.org/wiki/Serendipity

Why Discovery:

  • Discovery is an alternative to search
  • Discovery is finding things on the Internet that you couldn't find on your own
  • Discovery is about consumers experiencing something magical and entertaining with every click
  • Discovery is a more natural way to put great products and content in front of customers

Aggregate Knowledge pioneered the Discovery category in 2005. Our founders recognized there was a huge missing link in the way people searched and found information on the web. As founders of one of the first social networking sites, Tribe.net, they learned the reality of how people really found and shared information online. They took this knowledge and built something never seen before; a network that helps people find the things they love without having to search.

We understand that consumers have the answers to what is truly interesting and relevant on the web. We know the importance of observing user behavior anonymously and in aggregate. By looking at the sum of the parts, we can see connections between billions of pieces of content, products, photos, blogs, videos, advertising and user generated content on the web. These connections are where the magic of discovery lies.

We have learned that once you engage a consumer, they will keep clicking for more great content and they will keep buying more great products. We have learned how to attract consumer interest by helping them understand what millions of others have done on the Internet.

Discovery is everywhere. It is on websites. In emails. In advertising and affiliate promotions. Discovery is on the store floor. In cell phones. It's in the air around us. We are delivering discovery everywhere with the Pique Discovery™ Network.

http://www.aggregateknowledge.com/discexpertseries.html

In this series, academic and industry leaders explore the growing influence of discovery on consumer behavior and business’ bottom line.

Software veteran, John Furrier, interviews recognized experts within the fields of economics, psychology and computer science to explore the importance online discovery and its implications for online businesses. Panelists share insights from their personal research, identify best practices and suggest ways for businesses to leverage this important new communications and sales channel.

Look for upcoming interviews with collaborative filtering scientist and author John Riedl and personalization expert Yezdi Lashkari.

 

Title: Discovery Comes of Age
Paul Martino, CEO, Aggregate Knowledge

Discovery has moved from a simple recommendation engine to a whole new way of finding products and information online. In this podcast, Aggregate Knowledge CEO Paul Martino, a pioneer in Discovery, discusses “What is Discovery?” He’ll address the relationship of Discovery to search, personalization, behavioral targeting, and recommendation engines.

Paul Martino is the CEO and cofounder of Aggregate Knowledge, which is the fourth company that he has founded over his 20 year technology career. Martino was previously the CTO and founder of Tribe Network, which was acquired by Cisco. In addition to being a serial entrepreneur, he has held senior business development positions at Intertrust and SkyPilot. The highly scalable architecture of Pique is based on the research work Martino did on massively parallel graph algorithms while a Ph.D. candidate at Princeton University. Paul also holds a B.S. in Computer Science from Lehigh University and an M.S. in Computer Science from Princeton.

Title: The Paradox of Choice
Barry Schwartz, Ph.D.

Barry Schwartz, award-winning author of The Paradox of Choice: How More is Less, explains how the increasing demand for options actually decreases consumer confidence and satisfaction: people can be overwhelmed with too many choices. In this podcast, Schwartz discusses his research and how it can apply in the online world.  He gives practical advice for retailers on how they can delight their customers and be successful in the online world.

Barry Schwartz is the Dorwin Cartwright Professor of Social Theory and Social Action at Swarthmore College. He is the author of several books, including

The Battle for Human Nature: The Science, Morality and Modern Life

and

The Costs of Living: How Market Freedom Erodes the Best Things in Life

. His articles have appeared in many of the leading journals in his field including the American Psychologist.
