2. Intermediate Data Science Projects
2.1 Speech Emotion Recognition
Explore the complete implementation of Data Science Project Example – Speech Emotion Recognition with Librosa
Let’s learn to use different libraries now. This data science project uses librosa to perform Speech Emotion Recognition. SER is the process of trying to recognize human emotion and affective states from speech. Since we use tone and pitch to express emotion through voice, SER is possible; but it is tough because emotions are subjective and annotating audio is challenging. We’ll use the mfcc, chroma, and mel features and use the RAVDESS dataset to recognize emotion on. We’ll build an MLPClassifier for the model.
Language: Python

2.4 Driver Drowsiness detection in Python
Drive your career to new heights by working on Top Data Science Project – Drowsiness Detection System with OpenCV & Keras
Drowsy driving is extremely dangerous and around thousands of accidents happen each year due to drivers falling asleep while driving. In this Python project, we will build a system that can detect sleepy drivers and also alert them by beeping alarm.
This project is implemented using Keras and OpenCV. We will use OpenCV for face and eye detection and with Keras, we will classify the state of the eye (Open or Close) using Deep neural network techniques.
2.5 Chatbot Project in Python
Build a chatbot using Python & step up in your career – Chatbot with NLTK & Keras
Chatbots are an essential part of the business. Many businesses has to offer services to their customers and it needs a lot of manpower, time and effort to handle customers. The chatbots can automate most of the customer interaction by answering some of the frequent questions that are asked by the customers. There are mainly two types of chatbots: Domain-specific and Open-domain chatbots. The domain-specific chatbot is often used to solve a particular problem. So you need to customize it smartly to work effectively in your domain. The Open-domain chatbots can be asked any type of question so it requires huge amounts of data to train.

3. Advanced Data Science Projects
3.1 Image Caption Generator Project in Python
This is an interesting data science project. Describing what’s in an image is an easy task for humans but for computers, an image is just a bunch of numbers that represent the color value of each pixel. So this is a difficult task for computers to understand what is in the image and then generating the description in Natural language like English is another difficult task. This project uses deep learning techniques where we implement a Convolutional neural network (CNN) with Recurrent Neural Network( LSTM) to build the image caption generator.
Dataset: Flickr 8K
Language: Python
Framework: Keras

In this project, we’ll use R with algorithms like Decision Trees, Logistic Regression, Artificial Neural Networks, and Gradient Boosting Classifier. We’ll use the Card Transactions dataset to classify credit card transactions into fraudulent and genuine. We’ll fit the different models and plot performance curves for them.
Language: R
Dataset/Package: Card Transactions dataset
3.3 Movie Recommendation System
Explore the implementation of the Best Data Science Project with Source Code- Movie Recommendation System Project in R
In this data science project, we’ll use R to perform a movie recommendation through machine learning. A recommendation system sends out suggestions to users through a filtering process based on other users’ preferences and browsing history. If A and B like Home Alone and B likes Mean Girls, it can be suggested to A – they might like it too. This keeps customers engaged with the platform.
Language: R
Dataset/Package: MovieLens dataset
3.4 Customer Segmentation
Put the medal to the pedal & impress recruiters with Data Science Project (Source Code included) – Customer Segmentation with Machine Learning
This is one of the most popular projects in Data Science. Before running any campaign companies create different groups of customers.
Customer Segmentation is a popular application of unsupervised learning. Using clustering, companies identify segments of customers to target the potential user base. They divide customers into groups according to common characteristics like gender, age, interests, and spending habits so they can market to each group effectively. We’ll use K-means clustering and also visualize the gender and age distributions. Then, we’ll analyze their annual incomes and spending scores.
Language: R
Dataset/Package: Mall_Customers dataset
3.5 Breast Cancer Classification
Check the complete implementation of Data Science Project in Python – Breast Cancer Classification with Deep Learning
Coming back to the medical contributions of data science, let’s learn to detect breast cancer with Python. We’ll use the IDC_regular dataset to detect the presence of Invasive Ductal Carcinoma, the most common form of breast cancer. It develops in a milk duct invading the fibrous or fatty breast tissue outside the duct. In this data science project idea, we’ll use Deep Learning and the Keras library for classification.
Language: Python
Dataset/Package: IDC_regular
3.6 Traffic Signs Recognition
Achieve accuracy in self-driving cars technology with Data Science Project on Traffic Signs Recognition using CNN with Source Code
Traffic signs and rules are very important that every driver must follow to avoid any accident. To follow the rule one must first understand how the traffic sign looks like. A human has to learn all the traffic signs before they are given the license to drive any vehicle. But now autonomous vehicles are rising and there will be no human drivers in the upcoming future. In the Traffic signs recognition project, you will learn how a program can identify the type of traffic sign by taking an image as input. The German Traffic signs recognition benchmark dataset (GTSRB) is used to build a Deep Neural Network to recognize the class a traffic sign belongs to. We also build a simple GUI to interact with the application.
Language: Python
Dataset: GTSRB (German Traffic Sign Recognition Benchmark)
