内容説明

ThisvolumecontainspaperspresentedattheFifteenthAnnualConferenceon ComputationalLearningTheory(COLT2002)heldonthemaincampusofthe UniversityofNewSouthWalesinSydney,AustraliafromJuly8to10,2002. Naturally,thesearepapersinthe?eldofcomputationallearningtheory,a- search?elddevotedtostudyingthedesignandanalysisofalgorithmsformaking predictionsaboutthefuturebasedonpastexperiences,withanemphasisonr- orousmathematicalanalysis. COLT2002wasco-locatedwiththeNineteenthInternationalConferenceon MachineLearning(ICML2002)andwiththeTwelfthInternationalConference onInductiveLogicProgramming(ILP2002). NotethatCOLT2002wasthe?rstconferencetotakeplaceafterthefull mergeroftheAnnualConferenceonComputationalLearningTheorywiththe EuropeanConferenceonComputationalLearningTheory. (In2001ajointc- ferenceconsistingofthe5thEuropeanConferenceonComputationalLearning Theoryandthe14thAnnualConferenceonComputationalLearningTheory washeld;thelastindependentEuropeanConferenceonComputationalLea- ingTheorywasheldin1999. ) ThetechnicalprogramofCOLT2002contained26papersselectedfrom 55submissions.
