Overview of this book

<p><span id="description" class="sugar_field">Unsupervised Machine Learning Projects with R will help you build your knowledge and skills by guiding you in building machine learning projects with a practical approach and using the latest technologies provided by the R language such as Rmarkdown, R-shiny, and more. The areas this course addresses include effectively exploring and preparing data in R and RStudio and training, evaluating, and improving a model's performance (if needed). You will feel comfortable and confident after learning unsupervised and supervised Machine Learning algorithms.</span></p> <p><span id="description" class="sugar_field">In the first of the four sections comprising this course, we start by introducing you to concepts in Machine Learning, before then moving on to discuss projects in unsupervised Machine Learning. Next, we focus on two machine learning paradigms—K-Means Clustering and Principal Component Analysis—to grasp how they work and apply them to business Customer Segmentation (Market Segmentation Analysis). We finish the section by looking at the specific design aspects of Horizon 7 and how to approach a project, before finally looking at some example scenarios that will help you plan your own environment.All the work delivered into the R code script during the videos is available through nice html reports created by Rmarkdown.</span></p> <p><span id="description" class="sugar_field">By the end of the course, you will be able to train and improve real-world projects and models using unsupervised Machine Learning techniques</span></p> <p><span id="description" class="sugar_field">The code bundle for this video course is available at: <a href="https://github.com/PacktPublishing/Unsupervised-Machine-Learning-Projects-with-R" target="_blank">https://github.com/PacktPublishing/Unsupervised-Machine-Learning-Projects-with-R</a><br /></span></p> <h2><span class="sugar_field">Style and Approach</span></h2> <p><span class="sugar_field"><span id="trade_selling_points_c" class="sugar_field">Step by step practical approach to building real-world projects using unsupervised Machine Learning with R.</span></span></p>

Section 3
Model Diagnostics - How Do I Find K?
The aim of the video is to explore different techniques that can be used to select best number of clusters k from our data, while building k-means algorithm. - Explore some subjective methods that can help us to select the number k - Explore various R packages to select k - Understand some quantitative methods to select k - Aggregate all available methods and make them vote to select k
