being data scientist in the tech industry is one of the most rewarding careers on the planet today went and studied actual job descriptions for data scientist roles at tech companies and distilled those requirements down into the topics that you'll see in this course hands-on data science and python machine learning is really comprehensive we'll start with crash course on python and do review of some basic statistics and probabilitybut then we're going to dive right into over topics in data mining and machine learning that includes things such as bayestheoremclusteringdecision treesregression analysisexperimental designwe'll look at them all some of these topics are really fun we're going to develop an actual movie recommendation system using actual user movie rating data we're going to create search engine that actually works for wikipedia data we're going to build spam classifier that can correctly classify spam and nonspam emails in your email accountand we also have whole section on scaling this work up to cluster that runs on big data using apache spark if you're software developer or programmer looking to transition into career in data sciencethis course will teach you the hottest skills without all the mathematical notation and pretense that comes along with these topics we're just going to explain these concepts and show you some python code that actually works that you can dive in and mess around with to make those concepts sink homeand if you're working as data analyst in the finance industrythis course can also teach you to make the transition into the tech industry all you need is some prior experience in programming or scripting and you should be good to go the general format of this book is 'll start with each conceptexplaining it in bunch of sections and graphical examples will introduce you to some of the notations and fancy terminologies that data scientists like to use so you can talk the same languagebut the concepts themselves are generally pretty simple after thati'll throw you into some actual python code that actually works that we can run and mess around withand that will show you how to actually apply these ideas to actual data these are going to be presented as ipython notebook filesand that' format where can intermix code and notes surrounding the code that explain what' going on in the concepts you can take these notebook files with you after going through this book and use that as handy-quick reference later on in your careerand at the end of each concepti'll encourage you to actually dive into that python codemake some modificationsmess around with itand just gain more familiarity by getting hands-on and actually making some modificationsand seeing the effects they have
