Data Science Programming Cookbook

Data science is transforming modern tech, and mastering it is essential for anyone aiming to analyze data, build predictive models, and deploy cutting-edge AI systems. This Data Science Cookbook is your comprehensive roadmap to understanding core analytics, classical machine learning, and advanced generative AI using a hands-on, practical approach.

This book systematically guides you through the complete data science lifecycle, starting with environment setup, foundational mathematics, exploratory data analysis, and visualization. You will master classical supervised and unsupervised machine learning algorithms, ensemble methods, and neural network architectures. The guide further explores computer vision with OpenCV, natural language processing, transformer mechanics, generative AI, GANs, and parameter-efficient LLM fine-tuning using LoRA and prompt engineering. Backed by 127 recipes, it covers MLOps production deployment with Flask APIs, Azure ML, and model drift monitoring, concluding with capstone projects featuring real-time face detection, GPT-3 chatbots, synthetic image generation, and vector database image comparison.

By the end of this book, you will possess a job-ready understanding of data science, machine learning, and artificial intelligence, equipped with the practical skills needed to build, deploy, and scale real-world applications confidently.

WHAT YOU WILL LEARN
● Perform data processing EDA with Pandas, Seaborn, and web scraping.
● Train classical supervised models using Python and scikit-learn libraries.
● Apply K-means clustering and reduce feature dimensions using PCA.
