  1. Ricardo:Integrating R and Hadoop Team: #19 Presenter: Xiaozhe Wang YueGu

  2. Agenda • Background • Introduction to R • Disadvantages for Current Strategies • Introduction to Ricardo • Overview of Ricardo’s Architecture • Evaluation • Reference

  3. Background DataMiningExamples • Eg: • Amazon personalized recommendation of products • Netfix recommend the movies to the customer by the taste of this customer

  4. Introduction to R R’s functionalityforDataMining • Principal and independent component analysis • k-means clustering • SVM classification • Generalized-linear • Latent-factor • Bayesian • Time- series

  5. Introduction to R R: Simplified Method for Data Mining Kmeans Algorithm Kmeans on R

  6. Disadvantages for Current Strategies in Scalability for Data Mining Disadvantages for Current Strategies • Exploit vertical scalability • Limited • Expensive • Sample the dataset • Lose important features • Lose the accuracy • Large-scale management system(DMS) • Less functionality

  7. Introduction to Ricardo Ricardo: R and Hadoop

  8. Architecture Overview of Ricardo’s Architecture

  9. Evaluation Performance and Scalability • Object:Simulate a real recommender system • Original Netflix competition dataset • Jaqlrequires about twice as much time as raw Hadoop. • higher level of abstraction

  10. Conclusion Conclusion • Ricardo, a scalable platform
