实用数据科学和PYTHON机器学习(影印版)

从事Amazon和IMDB的机器学习算法相关工作的Frank Kane将指导你迈向数据科学世界的步。本书为你提供了理解和探究该领域核心主题所需的工具，以及构建和分析你自己的机器学习模型的信心和实践。借助有趣易懂的实例，Frank Kane以任何人都能理解的方式解释了贝叶斯方法和K-means聚类等潜在的复杂主题。基于Frank大获成功的数据科学课程，本书将使你能够使用Python分析数据并高效地执行机器学习。Frank会使用Python所提供的各种数据挖掘和数据分析技术帮助你挖掘数据的价值，开发有效的预测模型来预测未来的结果。你还将学习到如何使用Apache Spark对大数据开展大规模的机器学习。书中涵盖了准备待分析的数据、训练机器学习模型以及可视化很终数据分析。

弗兰克？凯恩，My name is Frank Kane. I spent nine years at amazon, 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.
