Data Handling and Numerical Computing

NumPy

• Foundation for fast mathematical computations with multi-dimensional arrays.

• Used for linear algebra, statistical analysis, and fundamental scientific calculations.

Pandas

• Provides robust data structures for manipulating, filtering, and analyzing structured data (tables, CSV, SQL, etc.).

• Essential for cleaning, transforming, and aggregating data across all engineering fields

Visualization

Matplotlib

• Core library for plotting and charting data, from basic line plots to complex 2D graphics.

• Ideal for custom visualizations in labs and reports.

Seaborn

• Simplifies statistical data visualization and makes attractive plots for complex data sets with minimal code, building on Matplotlib.

Scientific and Engineering Computation

• SciPy - Offers algorithms for integration, optimization, and advanced scientific computations—key for simulations, modeling, and engineering analysis.

• OpenCV- Leading computer vision toolkit for image processing, feature detection, and real-time video analysis, crucial in robotics and automation projects.

Machine Learning and Artificial Intelligence

• Scikit-learn- User-friendly library for essential machine learning methods (classification, regression, clustering).

• Perfect for quick experimentation with engineering datasets.

• TensorFlow & PyTorch- Industry standards for designing, training, and deploying deep learning models for advanced AI, autonomous systems, and industrial control.

• Keras- High-level neural network API, running on top of TensorFlow, for rapid prototyping and experimentation.

• PyCaret- Low-code automated machine learning toolkit for rapid end-to-end workflows, popular for engineering students venturing into applied AI projects.

Advanced Data Processing

• Dask- Enables scalable, parallel computation on large datasets that don’t fit in memory, extending Pandas-like syntax to distributed systems.

• Polars-  High-performance, columnar data manipulation alternative to Pandas—especially efficient for big data tasks and newer workflows.

Application Development and Automation

• Fast API - Modern, asynchronous web framework for quickly building APIs, ideal for Internet of Things (IoT), data dashboards, and automation tools.

• Requests- Simplifies HTTP calls for web scraping, API interactions, and data retrieval in automation and research.

Natural Language and Structured Data

• Beautiful Soup - For HTML/XML parsing and web scraping, useful for collecting online data for research or project inputs.

• NLTK / spaCy- Essential libraries for natural language processing, text mining, and working with engineering documentation or user feedback.
