R: Unleash Machine Learning Techniques by Cory Lesmeister

Key FeaturesBuild your confidence with R and find out how to solve a huge range of data-related problemsGet to grips with some of the most important machine learning techniques being used by data scientists and analysts across industries todayDont just learn – apply your knowledge by following featured practical projects covering everything from financial modeling to social media analysisBook DescriptionR is the established language of data analysts and statisticians around the world. And you shouldnt be afraid to use it...This Learning Path will take you through the fundamentals of R and demonstrate how to use the language to solve a diverse range of challenges through machine learning. Accessible yet comprehensive, it provides you with everything you need to become more a more fluent data professional, and more confident with R. In the first module youll get to grips with the fundamentals of R. This means youll be taking a look at some of the details of how the language works, before seeing how to put your knowledge into practice to build some simple machine learning projects that could prove useful for a range of real world problems.For the following two modules well begin to investigate machine learning algorithms in more detail. To build upon the basics, youll get to work on three different projects that will test your skills. Covering some of the most important algorithms and featuring some of the most popular R packages, theyre all focused on solving real problems in different areas, ranging from finance to social media.This Learning Path has been curated from three Packt products:R Machine Learning By Example By Raghav Bali, Dipanjan SarkarMachine Learning with R Learning - Second Edition By Brett LantzMastering Machine Learning with R By Cory LesmeisterWhat you will learnGet to grips with R techniques to clean and prepare your data for analysis, and visualize your resultsImplement R machine learning algorithms from scratch and be amazed to see the algorithms in actionSolve interesting real-world problems using machine learning and R as the journey unfoldsWrite reusable code and build complete machine learning systems from the ground upLearn specialized machine learning techniques for text mining, social network data, big data, and moreDiscover the different types of machine learning models and learn which is best to meet your data needs and solve your analysis problemsEvaluate and improve the performance of machine learning modelsLearn specialized machine learning techniques for text mining, social network data, big data, and moreAbout the AuthorRaghav Bali has a masters degree (gold medalist) in IT from the International Institute of Information Technology, Bangalore.
