Top 5 Data Science Projects in R For Beginners [2023]

The need for trained Data Scientists, AI specialists, and ML programmers is growing rapidly as more businesses and organizations hop on the Data Science bandwagon.

Employers only want to recruit people who have the necessary training, knowledge, and, most crucially, work experience.  To what extent, then, does "practical experience" refer to actual work experience? In that case, how about fresh graduates of an entry-level Data Science program?

Please note that when we refer to "practical experience," we are not referring to paid employment or work experience. Our focus here, however, is on the construction and development of actual Data Science projects. To advance in a Data Science career, hands-on experience with real-world projects is essential for every aspiring Data Scientist.

The actual difficulty, though, lies in locating the projects that are a good fit for your expertise, experience, and personal preferences. For this reason, we've put together a collection of great Data Science project ideas for beginners to work on in R.

Top Data Science projects in R for Beginners

1.   Sentiment Analysis project

Ensuring happy customers is a top priority for the vast majority of businesses and brands today. Knowing what your clients enjoy and don't like, what their preference patterns are, and most importantly what they need is the finest method to build a dedicated following.

The majority of businesses nowadays utilize sentiment analysis to learn how customers feel about their offerings. Sentiment Analysis, as the name suggests, examines written communication to discern the author's intended tone.

The Sentiment Analysis instrument classifies the words into positive, negative, and neutral binary based on its analysis. The 'janeaustenR' dataset/package will be used for this assignment. The project also makes use of general-purpose dictionaries like AFINN, Bing, and Loughran. Also, you will use a word cloud to represent the outcomes.

2.   Uber Data Analysis project

It's no secret that Uber is a company that lives and breathes data. The business collects and analyzes user information to develop personalized transportation services. While Uber is dedicated to making data-driven judgments, it also employs a combination of advanced data analytics and predictive analytics to build its marketing tactics, promotional offers, and pricing rules.

In this project, you’ll create a data analysis system utilizing the ggplot2 library to glean insights from user data and to make virtually exact predictions of clients who will enjoy Uber trips and rides. The system will use R programming and the ggplot2 library to evaluate numerous client parameters like the number of trips made in a day, the daily trip hours of recurring customers, the number of journeys over a given month, etc.

Using this information, the system can determine, for example, the typical daily usage of the Uber service, the busiest times of day, the days of the month, and the days of the week with the most trips.

3.   Credit Card Fraud Detection project

Credit card fraud has been on the rise recently. It is one of the most widespread threats to the BFSI industry. This R project's goal is to train a classifier to accurately identify potentially fraudulent purchases made with a credit card.

The project's dataset will be made up of credit card transactions, both legitimate and fraudulent. Many machine learning (ML) algorithms will be used in this research. These include Decision Trees, Logistic Regression, Artificial Neural Networks, and Gradient Boosting Classifier.

These ML algorithms will allow the system to distinguish between legitimate and fraudulent calls. Learn how to implement ML algorithms in a practical setting for classification with the help of this project.

4.   Movie Recommendation project

Recommendation engines are put to use by services like Amazon, Amazon Prime, and Netflix, which have many devoted users. As you would imagine by the name, a recommendation engine's only function is to “recommend” relevant things to customers - while for Amazon it advises merchandise, for Prime and Netflix it recommends material to users, depending on their past buy history or viewing history.

The primary focus of this R project is the creation of a movie-recommendation system. The MovieLens dataset was used for this investigation. In this project, you will construct an Item Based Collaborative Filter.

The great thing about making your movie recommendation engine is that you get to learn all about how recommendation engines work from the ground up. You will gain experience applying what you've learned about R programming and machine learning to a real-world scenario.

5.   Music Recommendation project

The main distinction between a movie recommendation system and a music recommendation system is that the former will suggest songs to listeners while the latter will suggest films. Project in Python and R.

KKBOX, Asia's most popular music streaming service, provided the dataset utilized in this research. Its collection includes more than 30 million songs. For this assignment, you will use Python and R to create a machine learning system that estimates how likely it is that a user would listen to a piece of music repeatedly after the initial listening event has occurred within a given time window.

Here, the listening habits of various people over a specific period are used to populate both the training and test datasets. So, for example, the system records the target as 1 in the training set if a recurrent listening event(s) triggers within a month after a user's first observable listening event, and otherwise as 0. Then, the test data follows the same procedure.

If you want to gain experience with EDA and use it to gain insights from data, this project is ideal.
