FeaturesFrom: Gregory Piatetsky-ShapiroDate: 16 May 2005 Subject: Measuring Quality of Data Mining Limericks Thanks to the few brave souls who were not afraid to send their poetry to the KDnuggets Limerick contest! For millenia, poets have not been able to come up with numeric quality measures for their work. This lead to disagreements, fights, Aegean wars, and other unfortunate events. However, data mining has a proud tradition of developing quality measures for rules, lift, data, etc. I relied on this research to develop what is probably the first objective and quantitative "limerick quality measure", which is:
The winner is
Who was quite the model designer He used Naive Bayes with gumption And even with the independence assumption Managed to predict an attriter! Adam Lynton, Australia, 15 points (10 words and the idea that Naive Bayes works well for the attrition prediction despite the independence assumption (:-) ).
2nd place for
3rd place is shared by There once was a data miner Who had an encounter with Bayes Sire The answer they sought Was he naive or not And decided to settle the bet on a fiver Vishwa Vinay, UK, 9 points (4 words and 5 points for the pun on the Naive Bayes). There once was a data miner, Who clamored for data finer, Her results were awash Though her techniques were so posh, "Give me," said she, "a table wider!" John Stultz, USA, 9 points (4 words and the idea of wider table, i.e. more columns, is better for predictive modeling) Honorable mention to There once was a data miner Who had moved on from 'geek' to 'high flier' Clustered, classified it all In kernel spaces, big and small Bending probability with a good prior Vishwa Vinay, UK, 8 points. There once was a data miner Who lived his life like an outlier He didnt have a single friend Because his work day would never end And as for the wife, he didn't mind her Vishwa Vinay, UK, 3 points. Data mining haiku results will be announced in the next issue. |
