Data Science Fundamentals and Practical Approaches - 2nd Edition

Data science is one of the fastest-growing fields in technology today, powering decisions across industries through data-driven insights, machine learning, and advanced analytics.

The book journeys from the fundamentals of data science to the advanced concepts and applications in the present-day computer vision techniques and data analysis. It covers the full data science pipeline, beginning with core fundamentals, ethics, and the analytics lifecycle, moving through data preprocessing, visualization, and a strong statistical foundation covering probability theory, Bayesian inference, and Monte Carlo simulation. This second edition expands on the first with two dedicated machine learning and deep learning chapters, adding AutoML, reinforcement learning, graph neural networks, transformer networks, and hybrid big data processing architectures.

By the end of this book, readers will emerge as competent data practitioners equipped with a thorough understanding of data science concepts. They will have gained the technical proficiency to use modern tools such as Python, PyTorch, TensorFlow, and data visualization tools, along with the analytical skills required for business problem-solving and data-driven decision-making across diverse real-world domains.
