And you shouldn't 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 you'll get to grips with the fundamentals of R. This means you'll 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 we'll begin to investigate machine learning algorithms in more detail. To build upon the basics, you'll 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, they're 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 Sarkar * Machine Learning with R Learning - Second Edition By Brett Lantz * Mastering Machine Learning with R By Cory Lesmeister Style and approach This is an enticing learning path that starts from the very basics to gradually pick up pace as the story unfolds. Each concept is first defined in the larger context of things succinctly, followed by a detailed explanation of their application. Each topic is explained with the help of a project that solves a real-world problem involving hands-on work thus giving you a deep insight into the world of machine learning.

詳細內容
R 是全球數據分析師和統計學家的主流語言。你不必害怕使用它……這條學習路徑將帶你了解 R 的基本概念,並展示如何使用這種語言通過機器學習解決各種挑戰。這是一個易於接觸但又全面的學習路徑,提供你成為更流利的數據專業人士和更自信使用 R 所需的一切。

在第一個模組中,你將掌握 R 的基本概念。這意味著你將查看語言運作的一些細節,然後看到如何將你的知識付諸實踐,構建一些可能對各種現實世界問題有用的簡單機器學習專案。在接下來的兩個模組中,我們將更詳細地研究機器學習算法。為了在基礎上進一步發展,你將參與三個不同的專案,這些專案將考驗你的技能。涵蓋一些最重要的算法,並使用一些最受歡迎的 R 套件,這些專案都專注於解決不同領域的現實問題,範圍從金融到社交媒體。

這條學習路徑是從三個 Packt 產品中精心策劃的:
* R Machine Learning By Example,作者 Raghav Bali, Dipanjan Sarkar
* Machine Learning with R Learning - Second Edition,作者 Brett Lantz
* Mastering Machine Learning with R,作者 Cory Lesmeister

風格與方法
這是一條引人入勝的學習路徑,從最基本的概念開始,隨著故事的展開逐漸加快步伐。每個概念首先在更大的背景中簡潔地定義,然後詳細解釋其應用。每個主題都通過解決涉及實踐工作的現實世界問題的專案來解釋,從而讓你深入了解機器學習的世界。
