Unlock the Power of Data EngineeringData is everywhere, but only with the right skills can you transform raw data into insights that drive impactful decisions. Data Engineering Core Techniques for Data Analysis with Pandas, NumPy, and Scikit-Learn is your comprehensive guide to mastering the essential skills needed to clean, transform, and prepare data for machine learning and analytics. With a focus on practical applications, this book equips you with the knowledge and confidence to take on real-world data challenges.
What You’ll LearnData Engineering Foundations is divided into three comprehensive parts, each building on the last to provide a complete understanding of data engineering
1. Essential Data Preparation and Manipulation TechniquesData Cleaning: Learn how to identify, handle, and transform missing and inconsistent data, ensuring that your datasets are accurate and reliable.Data Wrangling with Pandas and NumPy: Master core data manipulation techniques, including merging, filtering, aggregating, and reshaping data. With hands-on exercises, you’ll understand how to streamline and simplify complex data tasks using Pandas and NumPy.Efficiency and Performance Optimization: Understand how to handle large datasets efficiently by optimizing performance with NumPy and applying best practices in data manipulation. 2. Feature Engineering for Enhanced Model PerformanceFeature Transformation: Explore scaling, normalization, and encoding techniques, each tailored to make data more suitable for machine learning models.Handling Categorical Variables: Discover strategies to manage and encode categorical data, including one-hot encoding, target encoding, and frequency encoding.Advanced Feature Creation: Learn to create meaningful features that capture complex relationships, including polynomial features and interaction terms that boost your model’s predictive power. 3. Data Cleaning and Preprocessing for Real-World ProjectsOutlier Detection and Anomaly Handling: Identify and manage outliers to improve data quality and model stability.Dimensionality Reduction: Understand the value of Principal Component Analysis (PCA) and other techniques that streamline high-dimensional data, making it more manageable without sacrificing critical information.Building Reproducible Workflows with Scikit-Learn Pipelines: Automate and structure your data transformation steps using Scikit-Learn’s powerful pipeline functionality, ensuring consistency and reproducibility in data workflows. Hands-On Learning with Real-World ApplicationsEach chapter is packed with practical examples, exercises, and case studies to reinforce your understanding. You’ll work through examples from a variety of industries—such as healthcare, retail, and customer analytics—providing insight into how data engineering techniques apply across fields.
