We’ve created this post exclusively for aspirants who wish to enter the domain of Machine Learning. In this article, we will highlight some exciting Machine Learning projects in R. Since R is the top preference when it comes to statistical computing, it is the ideal choice for building Machine Learning projects.
Before we start our discussion on Machine Learning projects in R, you should be aware of the standard steps involved in building a Machine Learning project:
- Problem definition – Before you begin designing a Machine Learning project, you must define the problem statement, that is, what problem do you aim to solve with the model and how ML fits into the picture.
- Data preparation – You must study the dataset at hand and determine whether it’s a structured or unstructured dataset, whether it’s static or streaming, and how will it complement the problem definition. This stage mainly involves cleaning and preparing the data for processing.
- Algorithm evaluation – A Machine Learning project involves different ML algorithms. It is crucial to identify which algorithms best-suit the problem definition and guarantee maximum accuracy of the outcomes.
- Data features – In this phase, you will determine which elements or features of the dataset you will use for the Machine Learning project and how the already obtained insights affect the project.
- Modeling – You must choose a particular model structure and find ways to improve it. Also, you must compare this with other models to see which one is befitting for the problem statement.
- Testing – As the name suggests, testing means studying the outcomes of the model and find ways to improve it even further. It is vital to analyze how a small change impacts the overall outcome of the model and also how it affects the following steps.
So, without further ado, let’s get started!

Can machine learning be done in R?
Yes. R is used for many machine learning tasks. Classification, segmentation and regression are few tasks that can be done using R. The thing about R is that it comes with a wide variety of machine learning packages that can be used for different tasks. For instance, if you want to do regression then you can use randomForest package. If you are on the other hand interested in classification then you can use glmnet package.
What is supervised learning in machine learning?
Supervised learning is one of the most basic machine learning techniques. It is also a cornerstone of many other machine learning algorithms & tasks. The data used in this type of learning are labelled- these are known as supervised datasets. In this type of learning, the algorithm has to learn the mapping between the input variables and the output variables. The algorithm has to learn the rules governing the relationship between the inputs and outputs. It’s much easier for the learning algorithm to learn using this type of data as compared to learning from a dataset where the outputs are not labelled.
What is the difference between classification and regression in machine learning?
Classification is predicting the class label of data instances, whereas regression is predicting numerical values. We fit a linear model for regression and a non-linear model for classification. A simple example of linear regression is predicting the prices of used cars. To solve this problem, we need a model that takes the following features of an automobile into account: the car's length, weight, fuel efficiency, and so on. We then fit a linear equation to the data points. A good example of classification is predicting whether a patient will contract a certain disease based on their age, gender, smoking status, etc. In this case, we fit a non-linear model to the data points.
