Overview of this book

Data analytics with R has emerged as a very important focus for organizations of all kinds. R enables even those with only an intuitive grasp of the underlying concepts, without a deep mathematical background, to unleash powerful and detailed examinations of their data. This book will show you how you can put your data analysis skills in R to practical use, with recipes catering to the basic as well as advanced data analysis tasks. Right from acquiring your data and preparing it for analysis to the more complex data analysis techniques, the book will show you how you can implement each technique in the best possible manner. You will also visualize your data using the popular R packages like ggplot2 and gain hidden insights from it. Starting with implementing the basic data analysis concepts like handling your data to creating basic plots, you will master the more advanced data analysis techniques like performing cluster analysis, and generating effective analysis reports and visualizations. Throughout the book, you will get to know the common problems and obstacles you might encounter while implementing each of the data analysis techniques in R, with ways to overcoming them in the easiest possible way. By the end of this book, you will have all the knowledge you need to become an expert in data analysis with R, and put your skills to test in real-world scenarios.

Application of ML algorithms - image recognition system

Machine learning or ML algorithms are widely used in various domains and are generally a way of fine-tuning systems with tunable parameters, thereby making the system better with examples in a supervised or unsupervised way. Nowadays, researchers are pushing machine learning with the help of deep neural networks to perform outstanding tasks, which only humans were capable of doing before.

Though it is impossible to list every use case or example of machine learning, we will list some of the most prominent applications:

  • Identification of unwanted spam messages in emails
  • Segmentation of customer behavior for targeted advertising
  • Forecast of weather behavior and long-term climate changes
  • Detection of fraudulent credit card transactions
  • Actuarial estimates of financial damage of storms and natural disasters
  • Recommendation...
