Gregory I. Piatetsky-Shapiro (born 7 April 1958) is adata scientist and the co-founder of theKDD conferences, and co-founder and past chair of theAssociation for Computing MachinerySIGKDD group for Knowledge Discovery,Data Mining andData Science.[1] He is the founder and president of KDnuggets,[2] a discussion and learning website forBusiness Analytics,Data Mining and Data Science.
AJewish refugee from Soviet Union, Gregory Piatetsky was born inMoscow, Russia to Inna Mogilevskaya and mathematicianIlya Piatetski-Shapiro. He was admitted in 1970 to Physics-Mathematics School no. 2, a leading math school in Moscow.[3][4]
In March 1974, Piatetsky emigrated toIsrael with his family, studyingmathematics and computer science atTel Aviv University for one semester atTechnion.[5] He subsequently earned MS (1979) and Ph.D. (1984) degrees from NYUCourant Institute.[6]
In 1984, his first paper was published inSIGMOD, proving that secondary index selection is NP-complete by reducing it to a set cover problem.[7] In his dissertation, he proved that the greedy method for set cover has a lower bound of 1 - 1/e ~ 63% of the optimal.[8]
He joinedGTE Laboratories, where he worked on intelligent interfaces relating todatabases. In 1989, he proposed a new project at GTE called "Knowledge Discovery in Databases". The project created advanced prototypes, including KEFIR (Key Findings Reporter),[9] a system for analysis and summarization of key changes in large databases, which was a forerunner of systems likeGoogle Analytics Intelligence. A KEFIR prototype was applied to GTEhealth care data and received GTE's highest technicalaward.[10]
In 1997, he left GTE to join Knowledge Stream Partners (KSP), where he was Director and later Vice President and Chief Scientist.[11] In April 2000, KSP was acquired by Xchange, Inc.,[12] where Piatetsky served as VP and Chief Scientist.[11]
Piatetsky left Xchange in May 2001 to become a self-employedconsultant and focus on KDnuggets.[13]
In 1989, Piatetsky organized the first workshop on Knowledge Discovery in Data (KDD-89), held atIJCAI-1989 in Detroit, MI.[1] This workshop had over 60 attendees, including researchersRoss Quinlan andJaime Carbonell.[citation needed]
Piatetsky organized the next two KDD workshops, in 1991 and 1993.[1] WithUsama Fayyad andRamasamy (Sam) Uthurusamy, he expanded the workshops into an annual international conference onData Mining and was the General Chair of the KDD-98 conference.[14] He served as the chair of the KDD Steering committee until 1998, when theSIGKDD group was formed as part ofACM to run the annual KDD conference and help promote research in Knowledge Discovery and Data Mining. He served as Director of SIGKDD for 2001–2005 and as SIGKDD Chair for 2005–2009.[15]
In 1997, Piatetsky and Ismail Parsa initiated theKDD Cup competition, which was the world's first open data mining contest.[16]
The annual ACM SIGKDD conference is the leading research conference on Knowledge Discovery and Data Mining, according to Microsoft Academic search[17] andGoogle Scholar.[18] The 21st ACM SIGKDD conference was held in Sydney, Australia in August 2015.
In 1993, Piatetsky started Knowledge Discovery Nuggets (KDnuggets) as a newsletter to connect researchers who attended the KDD-93 workshop. With the emergence of the Internet andMosaic, he and Chris Matheus eventually created the website: Knowledge Discovery Mine,[19] hosted at GTE Labs. The newsletter served as an unofficial publication of KDD workshops. When Piatetsky left GTE Labs, he created the KDnuggets website,[20] with the mission of covering the field with short, concise "nuggets". The resource started as a directory for the subjects of data mining and data science, including Software, jobs, academic positions, CFP (calls for papers), companies, courses, datasets, education, meetings, publications and webcasts.
KDnuggets' main focus is to cover the fields of Business Analytics, Data Mining, and Data Science, includinginterviews with key leaders. It offers a free data mining course for advanced undergraduates or first-year graduate students.[21]

In February 2015, Piatetsky and Data ScienceTech Institute announced a partnership and he became an Honorary Member of its Scientific Advisory Board.[22]
In 1991, Piatetsky and William (Bud) Frawley edited their first bookKnowledge Discovery in Databases. In 1996, Piatetsky,Usama Fayyad,Padhraic Smyth, andRamasamy Uthurusamy edited a follow-upAdvances in Knowledge Discovery and Data Mining.[23]
Piatetsky also helped launch and co-edit theData Mining and Knowledge Discovery journal.[citation needed] He authored 9 edited books and collections and over 60 technical papers, articles and book chapters, mostly focusing on data mining and knowledge discovery.[citation needed].
Gregory Piatetsky-Shapiro has received the first ACM SIGKDD Service award for starting the KDD conferences and contributions to the KDD community, including KDnuggets newsletter. Dr. Piatetsky-Shapiro is the founder of the Knowledge Discovery in Database conference series (KDD, now the ACM SIGKDD International Conference on Knowledge Discovery and Data Mining).
