作者簡介

  My name is Frank Kane. I spent nine years at ******, corn and imdb. corn, wrangling millionsof customer ratings and customer transactions to produce things such as personalizedrecommendations for movies and products and people who bought this also bought. I tellyou, I wish we had Apache Spark back then, when I spent years trying to solve theseproblems there. I hold 17 issued patents in the fields of distributed computing, data mining,and machine learning. In 2012, I left to start my own successful company, Sundog Software,which focuses on virtual reality environment technology, and teaching others about bigdata analysis.
