Top Data Science Project Ideas You Should Consider Learning
Movie Recommendation System (Easy)
With the onset of movie streaming and video-on-demand services becoming more and more popular with passing days, it is very clear that online streaming platforms like Netflix and Amazon are making full use of Data Science to attract more viewers to their platforms and also help retain the existing customers.
Here, you are given recommendations based on your preferred genre and the shows or movies that you have previously watched and liked. This is done by making use of various concepts such as Deep Learning and Artificial Intelligence.
By making use of a dataset such as the MovieLens dataset, you can be on your way to build a good movie recommendation system. By tracking the similarity and patterns in viewing, collaborative filtering can be implemented to put forth a recommendation. Content-based filtering is also an important aspect where users’ history plays a crucial role in recommending movies effectively.
Customer Segmentation System (Easy)
Companies that involve working on a B2C-based model need customer segmentation always. Because with segmentation, the companies can spend their time and resources in targeting potential user base and also understanding the best customers for their product.
The process involves three simple steps:
- Identifying the potential customer base for product sales
- Implementing clustering algorithms to group similar customers together
- Providing customized solutions to each of the clustered groups
Clustering techniques are championed here to identify the segments in which customers’ behavior can be traced to put forth a customized campaign. K-means clustering algorithm is a very widely used technique for clustering when working with an unlabeled dataset.
Segmentation based on age, annual income, country of origin, or even spending amount can easily be analyzed and understood, thereby helping the companies leverage the concepts of Data Science and turn them into something lucrative.

Sentiment Analysis Modeling (Intermediate)
Among the thousands of organizations out there, a majority of them make use of sentiment analysis to check and assess the attitude of their customers toward the products offered by them. This is one of the vital steps used to analyze gaps in business processing and to sense potential growth.
The sentiment can be analyzed as positive, neutral, or negative by analyzing the text and presenting the user with a scorecard based on the presence of certain words by mapping it from the dataset. The most popular way to analyze sentiment has been by making use of the data from Twitter. Users’ tweets can be used for analysis. This could be a very good Data Science project that you could use for learning and implementation.
Credit Card Fraud Detection Analysis (Intermediate)
Security has been the primary concern of the 21st century. With multiple ways of fraud coming into the limelight, the world of Data Science helps curb all of this. This project aims to quickly detect a fraudulent transaction on a credit card and possibly alert the user or block the card. One common situation is that a user swipes the card in a location in the USA and, in the next couple of minutes if it is traced to being used somewhere in Europe or Asia, then this would pose as a black flag, thereby rejecting the transaction.
This method uses classifiers built on a variety of Machine Learning algorithms to detect such an anomaly. The process of feature extraction, alongside training models and testing predictions, is very vital here. Increasing the level of accuracy in terms of detection can be beneficial overall.

Amazon vs eBay (Advanced)
We have all been in a situation where we buy an item online only to see it priced cheaper elsewhere. With the help of Data Science, it becomes very easy to find the price difference for a product and eventually calculate the total spending.
Let’s say, we use a dataset with 3,500 products, and the cart value is somewhere around US$193,000 by picking up items from the most expensive seller. The best case is seen to be around US$149,000. Here, there is a whopping 23 percent (US$44,000 worth) saving! So, all it took was a comparison between the top e-commerce sites and their offerings for the same product.
Next up on this Data Science projects in Python blog, let us check out the skills that are needed to work on these data science project ideas.
Skills Needed for Data Science Projects
Since Data Science poses to be a convoluted field to a nascent learner, it is vital that you understand all the skills that play an invaluable role in the process of end-to-end completion of projects.
It is quite popular in the field of Data Science that most of the time spent in working on a project goes into cleaning data during the preprocessing stage. In fact, almost 80 percent of the time is spent on this. Working on your skills to master data cleaning will not only ensure you have a smooth path in the projects but also will make you more valuable in terms of being a potential candidate for employment.
If you are wondering where you can go to look for data, I would suggest you check out the Data.gov website. There is a topic-wise search option that will help you get your hands on this data and begin working. Quora can also be a great source for finding some messy data which is the need of the hour to sharpen your preprocessing skills.
After getting your hands on the data, you need a tool such as the Pandas library in Python to work with the data across DataFrames and drop a couple of columns if they do not add any value to the data. If you prefer programming with R, then the dplyr package can be considered.
Exploratory Data Analysis
One of the key reasons for the implementation of Data Science can be seen through Exploratory Data Analysis (EDA). This is a process that involves the generation of questions and trying to find answers to those questions by making use of visualizations. It is very vital to do so because it allows you to understand your data better and gives you a chance to make unintended discoveries as well.
One of the good sources where you can find EDA datasets is the IBM Analytics Community. After the dataset is obtained, various tools and libraries can be used to perform the analysis. Matplotlib is a widely used Python library which is used for EDA. On the other hand, ggplot2 is also a wonderful package to work with if you are an R user.
Interactive Data Visualization
The creation of beautiful-looking visualizations and dashboards is something that sets apart an exceptionally sound Data Scientist from a person who’s not very inclined to do this. The creation of visualizations helps immensely even when implemented for business-related outcomes.
Dash is one of the nicest libraries for Python that can be used to create stunning dashboards in a rapid manner. In the case of R, there is Shiny, which is a great tool that can be used for interactive visualizations.
Some of the important points that you need to keep in mind when creating dashboards:
- Know the requirement from your audience
- Creatively put across a story
- Use good-looking visualizations
- Keep it simple

If you are serious about building a portfolio in Data Science, Machine Learning is a must. Rather than delving into a complex Deep Learning project, it is suggested you keep it simple and work from the basics. When it comes to Machine Learning, it is always considered a good start to work with concepts such as linear regression and logistic regression.
Python offers learners with the Scikit-learn library, which is a pleasure to work with. It covers all of the concepts such as classification, regression, clustering, and preprocessing data and helps in model selection as well. For R users, the Caret package is a very well-rounded package that can be used to implement Machine Learning in R.
To have the most impact when you work with Machine Learning projects, make sure to work on a dataset that has a noticeable business impact. Everything from loan default detection to credit card fraud detection can be used when working with Machine Learning.
On a final note, one of the primary skills that you should be working on, alongside all the above-mentioned concepts is your communication skills. It is one of the key components that set apart a good Data Scientist from the great.
It would not be of much value if you could design the most efficient models or create the most detailed analytics but cannot convey the same to either a customer or a fellow teammate. It always helps if you practice this skill and add it to your portfolio.
Direct communication in the field of Data Science can come through collaboration by making use of Jupyter Notebooks or R Markdown files. Documenting all of these on your GitHub will help in a good manner when communicating with potential employers as well.
