齐伟

Qi Wei is an author about whom little public information is available; no systematic account of his identity or career has yet appeared. His two works in the library nonetheless indicate his main writing interests. He focuses on artificial intelligence and programming design, and is the author of Data Preparation and Feature Engineering: Essential Skills for Data Engineers and Mathematical Foundations of Machine Learning. The first addresses practical aspects of data engineering, including data cleaning, organization, and feature construction; the second returns to the mathematical principles behind machine learning, helping readers build a theoretical foundation. Together, the two books show a style that values both fundamentals and hands-on practice, with clear and accessible language suitable for beginners and advanced readers alike.
