8 Astonishing Data Science Projects in R For Beginners [2021]

Do you wish to enter the Data Science field?

Do you want to develop innovative Data Science tools and solutions?

If yes, you’ve stumbled across the perfect article! In this post, we’ll share with you some of the most exciting Data Science project ideas for beginners.

Why work on Data Science projects?

As more companies and organizations are joining the Data Science bandwagon, the demand for qualified and skilled Data ScienceAI, and ML experts is escalating rapidly. While this is a promising opportunity for millions of Data Science aspirants and professionals, bagging a Data Science job role isn’t a cakewalk. Companies only hire candidates who have the right educational qualifications, skill set, and most importantly, practical experience.

So, does practical experience mean work experience? And if so, what about beginners who’ve just completed their Data Science training?

When we say “practical experience,” we do not mean professional work experience. Instead, we’re talking about building and creating real-world Data Science projects. For every Data Science aspirant, working on live projects is an important stepping stone toward building a successful Data Science career. 

Projects offer you the opportunity to implement your theoretical knowledge and skills in real-world scenarios. This not only helps to strengthen your knowledge base and sharpen your skills, but it also helps build your confidence. What’s more, is that in a market characterized by cut-throat competition, employers always prefer candidates who have the “X” factor. Thus, the projects you build can set you apart from the crowd of equally qualified aspirants.

However, the real challenge comes while finding the right projects according to your qualifications, skills, and interests. This is why we’ve compiled a list of perfect Data Science project ideas in R for beginners!

Data Science projects in R

1. Sentiment Analysis project

Customer satisfaction is one of the most crucial goals of almost every company and brand now. The best way to create a fanbase of loyal and satisfied customers is to get into their psyche – understand their likes and dislikes, identify their preference patterns, and most importantly, their needs. Sentiment Analysis is the tool that most companies use to understand the attitude of their target audience toward their products/services.

As the name suggests, Sentiment Analysis analyzes the words to identify the underlying emotions of the people expressing them. By analyzing the words, the Sentiment Analysis tool categorizes them under two binaries – as positive, negative, and neutral. In this project, you’ll use the ‘janeaustenR’ dataset/package. Other tools used in the project include general-purpose lexicons such as AFINN, Bing, and Loughran. Also, you will use a word cloud to display the outcomes.

2. Uber Data Analysis project

Uber is a data-driven brand through and through. The company mines and leverages user data to craft the best-suited cab solutions for its customers. While Uber is invested in making data-driven decisions, it also leverages a combination of advanced data analytics and predictive analytics to design its marketing strategies, promotional offers, and pricing policies.

In this project, you’ll design a data analysis system using the ggplot2 library to gain insights from user data and to generate nearly accurate predictions of customers who will avail Uber trips and rides. The system will use R programming and the ggplot2 library to analyze different customer parameters like the number of trips made in a day, the daily trip hours of repeat customers, the number of trips during a particular month, etc.

By visualizing these data points, the system can figure out the average number of passengers that avail Uber trips in a day, the peak hours when there’s maximum traffic in the app, the days with the highest number of trips in a month, and so on.

3. Credit Card Fraud Detection project

Of late, credit card frauds have skyrocketed. In fact, it is one of the most prevalent menaces of the BFSI sector. The idea behind this R project is to develop a classifier that can efficiently detect credit card fraudulent transactions.

The dataset for the project will be credit card transaction dataset containing a mix of both non-fraudulent and fraudulent transactions. The project will include numerous ML algorithms like Decision Trees, Logistic Regression, Artificial Neural Networks, and Gradient Boosting Classifier.

By implementing these ML algorithms, the system will be able to tell apart a fraudulent call from a non-fraudulent one. This project will teach you how to apply ML algorithms in a real-world scenario to perform classification.

4. Movie Recommendation project

If you’re an avid lover of Amazon, Amazon Prime, or Netflix, you probably know that these platforms leverage “recommendation engines.” As you can guess by the name, a recommendation engine sole purpose is to “recommend” relevant things to customers – while for Amazon it recommends products, for Prime and Netflix it recommends content to users, based on their previous purchase history or watch history.

The main goal of this R project is to design a recommendation system that will recommend movies to users. The dataset used for this project is MovieLens dataset. This data includes 105339 ratings for over 10329 movies. In this project, you will create an Item Based Collaborative Filter.

The best part about building this movie recommendation engine from scratch is that it will help you understand the inner functioning and mechanism of a recommendation engine. You will learn how to implement your R programming skills along with Machine learning skills in a live project.

**5. Music Recommendation project **

A music recommendation system works similarly to a movie recommendation system, the only difference being that instead of movies, it will recommend music to users. This is a Python + R project. The dataset used for this project is from KKBOX, the leading music streaming service in Asia, boasting of a library containing over 30 million music tracks.

In this project, you will build an ML system using Python and R that can predict the chances of a user listening to a song on loop after the first listening event was triggered within a specific time window. Here, the training and test datasets are chosen from the listening history of different users in a given time period.

So, for instance, if a recurring listening event(s) triggers within a month after a user’s first observable listening event, the system marks the target as 1 in the training set, and otherwise, it marks 0. The same rule is then applied to the test set. This project is the perfect opportunity to learn how to perform basic EDA to derive insights from the data.

6. Customer Segmentation project

Just like Sentiment Analysis is used to gain deeper insights into the customers’ opinions and emotions about different products/services, Customer Segmentation is used for more targeted marketing. By categorizing the target audience into different buyer personas according to their needs, preferences, age, location, job, purchasing behavior, etc., brands can create customized products, marketing strategies, and offers/discounts, for a specific customer segment. This allows for higher customer satisfaction which eventually boosts the sales and revenue.

Customer Segmentation is one of the most extensively used applications of unsupervised learning (ML). In this project, you will use the K-means algorithm for clustering an unlabeled dataset. The K-means clustering algorithm can effectively visualize the age and gender distributions in the dataset. Further, it will also analyze annual incomes and spending patterns. Essentially, this R project will offer a descriptive analysis of the data by implementing varied versions of the K-means algorithm.

7. Product Bundle Identification project

The concept of product bundling is nothing new in the field of marketing. In the product bundling approach, different products are clubbed together and sold as a single unit at a specific price (usually discounted price). This allows marketers to encourage customers to buy more of their products. Perhaps the best example of a product bundle is McDonald’s Happy Meal.

In this Data Science project, the primary focus will be on subjective segmentation, a clustering technique that can help identify the best product bundles in sales data. Here, we will take a weekly sales transaction dataset containing the purchased quantities of different products over the span of a few weeks.

The dataset will also include normalized values. By using this dataset, the goal is to find out which products can be bundled together to make excellent combos for customers. While the traditional approach uses the Market Basket Analysis to identify product bundles, in this project, our focus is to compare and analyze the relative importance of time series clustering in determining product bundles from sales data.

8. Wine Quality Prediction project

The idea here is to improve wine quality using predictive modeling. In this Data Science project, we will analyze a red wine dataset to assess the wine quality. The objective of this project is to explore the chemical properties that influence the quality of red wine.

In the project, the first consideration is to use the input variables to predict the wine quality, whereas the second consideration is to classify wines having excellent attributes. You will create and refine plots to illustrate the unique relationships in the data as and when they are uncovered. The project will teach you data exploration, data visualization, storytelling, and also how to apply regression models and ask the right questions for data analysis at different stages in the project.
