  • Difficulty Level : Medium
  • Last Updated : 17 Aug, 2021

Data Science and its subfields can demoralize you at the initial stage. The reason is that understanding the transitions in statistics, programming skills (like R, Python), and algorithms (whether supervised or unsupervised) are tough to remember as well as implement. Are you planning to leave this battle without fighting thinking you are just a beginner? This will make the situation more complicated and to rescue yourself, what you should be doing is gaining some hands-on experience by doing projects & solving real-time problems speedily and profitably. 


Let’s take a look at fewer project ideas revolving around the notions of Data Science which won’t only brush your skills up but also make an everlasting impression on the recruiters’ minds.

1. Fake News Detection Using R Language

Fake News is prevalent everywhere and it disperses 10X faster than real news. This is an enormous source of trouble that has impacted every orbit of a common man’s life. Due to this, many problems occur like political polarization, other cultural conflicts, and violence. Thinking how this problem could be tracked and tackled well! This Fake News Detection project prepared from R Language’s dataset labels real and fake news well along with an appropriate representation of the textual information. Later, we may incorporate the notions of NLP i.e. Natural Language Processing and TF-IDF Vectorizer technique (whose full form is term frequency-inverse document frequency vectorizer) for an excellent approximation of what is real or fake? So, one needs not to feel fearful whether social authenticity is achieved because the labelization or classification done by NLP, TF-IDF Vectorizer examines the dataset of dimensions 7796*4 well and executes impeccably on Jupyter Lab whose web-based environment supports workflows of scientific computing as well as Natural Language Processing in a flexible and configurable manner.

2. Creating your First Chatbot In Python

Chatbots are a way through which organizations may achieve customer-centricity by tracking and resolving all the real-time issues of customers well. Thinking about how this is achievable in real-time! There are some conversational NLP scripts running in those chatbots through which they understand the questions and then, reciprocate the solutions in the form of customer-oriented feedback. In this project, Python language accesses a larger volume of data via Intents JSON file for finding the patterns well. Those patterns will be helpful in returning appropriate responses the user desires to acquire for solving his/her problem. If required, such responses may be synchronized with necessary customizations thereby handling open-domain or domain-specific problems well. On an overall basis, choosing this project will not only be helping you learn more about Python and its libraries but also make you understand the decoding principles chatbots use for generating the responses assertively solving concurrent or future issues of a customer keeping in mind the accuracy and trustworthiness of feedback.

3. Detecting Frauds of Credit Cards via Python

Credit Card frauds are omnipresent in the pandemic era and are majorly performed by scammers. Such people are smart enough to steal your credit card details like CVV and Card Numbers and use that to access your account without your knowledge. Since a variety of digital ways are there to access someone’s account, the chances to catch such fraudulent scammers almost become low. Thinking about how one can increase the rate of catching such scammers! With this CC Fraud Detection i.e. Credit Card Fraud Detection project encompassed with hidden capabilities of Machine Learning, ANN i.e Artificial Neural Network, and decision trees, insights into the customers’ data will be labeled with appropriate modeling of their spending behavior. Those who are spending more will obviously be tracked by such scammers so that they may steal the financial freedom of those users well. With such tracking, the chances of prohibiting such fraud people from doing what they really want to become higher thereby preventing the privacy of information well with overall accuracy.  

4. Using Deep Learning for the Classification of Breast Cancer

Breast Cancer is the second most common cancer spotted worldwide since its awareness programs are rarely conducted. You may think that in this technologically advanced world full of solutions one can smartly fight the battle of breast cancer! This is appropriate to some extent but if a delay occurs those solutions won’t be doing the miracles. So, this is essential to identify the traits of such cancer and you may also contribute to this by opting for Breast Cancer Classification as your project. Here, the dataset would be IDC i.e. Invasive Ductal Carcinoma as this is the most usual manifestation of breast cancer found in more than 70 percent of the patients. The benefit is that this dataset will synthesize all the diagnostic images of cancer-inducing cells and with help of Deep Learning attributes, the classification of patients (either they are suffering from this type of cancer or not) will be done precisely so that it is easier to identify the complexity of a patient’s situation. Later, if required, the analysis will be used wisely for the patient’s benefit thereby helping him/her recover from the consequences of breast cancer as soon as possible.

5. Implementing a Driver Fatigue Detection System 

Driver Fatigue or Drowsiness is one of the key contributions to road accidents. As per the IEEE Survey, more than 30 percent of the accidents occurring day/ night are due to the frequent sleepiness drivers commit while traversing to longer or shorter routes. What if we find such a system that detects such fatigue anytime? This is possible with the real-time implementation of a driver drowsiness project which requires a webcam and some libraries of Python programming language (those libraries would be Keras, Open CV). The webcam will be doing face recognition while on the other hand Keras and Open CV will also be offering valuable contributions. They would be like Keras will examine whether the driver’s eye is closed or open (you will find the contrivance of Deep Neural Network techniques while using Keras); Open CV will scan the eye and face of the driver. As the driver falls asleep, these libraries and webcam come into action and force the triggering of the alarm for the sake of alerting the driver. Such a project can reduce the increase in the number of road accidents and also ensures public safety round-the-clock.

6. Movie Recommendation Platform with R Packages

Movie Recommendation Platform will work similarly to Netflix, Youtube, Hotstar. This will utilize R packages and predict the recommendations keeping in mind the users’ preferences, star cast, genre, and browsing history. Still wondering how this system will be beneficial! The system can possibly fill all the deficiencies of movie searches just by telling the choices accepted by the variability of users. Besides, the project can be created through two different techniques – a) Collaborative Filtering b) Content-Based Filtering. In Collaborative, a past behavior approach of a user towards movies will be considered to predict outcomes regarding what to watch or not? On the other side, content-based filtering utilizes a series of discrete characteristics totally based upon the description and profile of a movie watched recently or in the past. In both of these, R packages like data.table, ggplot2, and recommenderlab can be used for modeling the desired movie recommendations precisely and in a fun-loving manner. So, you must select this platform as your project and train it well for classifying and recommending movies with different concepts and tastes.

7. Sentiment Analysis Backed by R Dataset

Sentiment Analysis is really helpful as it identifies the subjective information from the available source material which businesses may use for understanding social sentiments. These sentiments give businesses an overview of what their customers talk about a brand or other associated services offered. Figuring how to initiate such analysis in real-time! With the computational power of R datasets (such as janeaustenr) and some general-purpose LEXICONS, we will be classifying negative and positive emotions of the number of people commented or mentioned with the contextual relevance. Later, some scores will be assigned to those sentiments ranging from 0 to 9, and with all this, businesses can make useful decisions or re-create their pre-decided strategies since this sentiment analysis platform has provided them meaningful insights after analyzing all the social media comments with a deeper meaning related to a brand or a service. Thus, beginners may start working on this project to analyze how one should be extracting meaningful game-changer insights from the analysis performed for a particular brand, service.

8. Prediction of Age & Gender through Deep Learning

Predicting the age and gender of an individual is harder than one thinks because such a prediction demands accuracy and consistency. Afraid if you should put your pedal in this challenging project! If you are a beginner and planning to impress your interviewer with critical thinking and CNN (i.e. Convolutional Neural Network) Implementation, this project would be an ideal choice for drawing the attention of the panel members. The prime aim is to detect the age and gender of a person after analyzing his/her picture. For accomplishing this, we will be using a DL model (rather than a regression model), package OpenCV, and dataset Adience. But some challenges would be there which we can’t afford to ignore. They are dim lighting, out-of-the-way facial expressions, and cosmetics applied on the skin. With them, it is possible to have multiple incompetencies while predicting larger degrees of variations during age prediction and gender detection. Henceforth, such challenges coming forward in the form of anomalies mustn’t be neglected. Instead, we should cross-check if their occurrence exists and focus more on filtering thousands of ages and genders tuning well with the exact identification of the age and gender.

9. Recognition of Emotions of a Speech with Librosa

Emotions are originated due to strong or low feelings when one exposes himself/herself to differing circumstances. Those circumstances are breakups, happy hours, client deadlines, or presenting your skills in front of the panel. What you should be thinking now is about a platform that analyzes such an emotional variance. Yes, the platform is available and has the name Speech Emotion Recognition. One can prepare this through the Python language and its packages named NumPy, PyAudio, Librosa, Sklearn, and SoundFile. The dataset would be RAVDESS whose full form is Ryerson Audio-Visual Database of Emotional Speech and Song. It consists of more than 7200 sound files and you are free to use any of them for emotion recognition. Moreover, the packages used are the building blocks of audio and music analysis which will describe how an emotion appears in real-time? Since emotions are challenging in their own way, you must be attentive while examining the pitch of human emotions like hatred, joy, and depression. On an overall basis, this platform is a fun project for beginners always trying to model speech signals with their respective emotions to restructure their actions with respect to needs and their surroundings. 

10. Segmentation of Customers’ Groups with ML

ML algorithms demand creativity and exemplary research so that they may be implemented in real-time in the most simplest and understandable form. From those algorithms, unsupervised learning ones are counted in the difficult ones but they model well the users’ requirements. We will be using K-means unsupervised learning algorithm (this one is simpler than others) for segmenting the customers. Such segmentation is impacted by factors like their annual income, buying and selling patterns, age, gender, and interests. Language would be R and dataset – Mall_Customers. You may ask about its benefit and the answer is – executing an online marketing campaign for fulfilling business needs. As a result of this project, one (data science beginners are included) can’t only segment the customers well but also analyze when the businesses should execute their marketing campaigns on the available customer bases for extracting profit margins and gaining popularity worldwide. In a nutshell, you, or the beginners are well-prepared in helping the ventures out structure their products and services well around their targeted customers and excite the customers by introducing what they really aspire for?
