7. Predicting the Severity of Road Accidents
Project Overview: Apply ML to public safety data. Develop a solution to predict the risk of road accidents based on environmental factors such as weather, lighting, and road conditions.
8. Credit Card Fraud Detection
Project Overview: Protect the financial ecosystem by identifying fraudulent transactions in real time. This project tackles the “needle in the haystack” problem: where fraud accounts for less than 0.1% of the data. You will go beyond the simple stages to use the Anomaly detection algorithms.
Phase 3: Natural Language Processing (NLP)
Teach machines to understand, interpret, and process human language and voice signals.
9. NLP implementation of “OK Google”
Project Overview: Learn the mechanics behind voice-activated systems. This project demonstrates how to implement speech-to-text functionality focused on real-time audio keyword searches and deep learning.
10. Quora Duplicate Question Identification
Project Overview: Solve the classic semantic problem. Build a model that determines whether two questions in a forum are statistically similar, helping to reduce content bias and improve user experience.
11. Topic Modeling (using LDA)
Project Overview: Identify and remove invisible titles from a long list of documents. This project teaches efficient data retrieval and storage as well as using LDA to find similarities in a dataset.
12. Gender Identification Based on Name
Project Overview: Explore the basics of text classification by training a model to predict gender based on first words. This project introduces NLP preprocessing and pipeline stages.
Section 4: Recommendation Programs
Build the engines that drive engagement on the world’s largest content and e-commerce platforms.
13. Smart Movie Recommender
Project Overview: Use collaborative filtering to build a personalized entertainment recommendation system. This project includes algorithms used to predict user preferences based on social ratings.
14. Spotify Music Recommendation Engine
Project Overview: Suggest tracks based on audio characteristics such as tempo, danceability, and energy. This project uses clustering (unsupervised learning) to find songs that “like the vibe” of a user’s playlist.
15. Course Recommendation Program
Project Overview: Build a system like Coursera or Udemy. Use Python to build an engine that suggests online courses based on a user’s previous reading history and interests.
Section 5: Advanced Theory and Statistics
High value projects include deep learning, computer vision, and complex data visualization.
16. Image Matching for Google Images
Project Overview: Learn how to use vector embedding in visual search. This project uses embedding to identify and match visually similar images within a large dataset, illustrating the collection features of Google Images.
17. Open Source Logo Detector
Project Overview: Build a computer vision model that identifies and locates corporate logos in various locations. Perfect for learning about object discovery (YOLO) and product monitoring.
18. Handwritten Digit Recognition (MNIST)
Project Overview: The “Hello World” of computer vision. Build a Convolutional Neural Network (CNN) that can recognize handwritten digits with high accuracy using deep learning.
19. WhatsApp Chat Analysis
Project Overview: Perform end-to-end data analysis on personal communications. Extract and visualize chat logs to gain insights into message patterns, user activity, and sentiment trends.
20. Customer Segmentation (K-Means)
Project Overview: Help businesses understand their audience. Use unsupervised learning to group customers based on purchase and age behavior for targeted marketing.
21. Analysis of Stock Price Movements
Project Overview: Use Deep Learning to analyze time series data. This project uses LSTMs to predict the movement of stock prices based on historical closing data.
