Machine learning appears quite different when data exceeds the capacity of a single system. In this section, learners explore the foundational ideas behind machine learning in big data environments and how familiar approaches change at scale. You will examine supervised and unsupervised learning, regression and classification problems, and the practical challenges that arise with massive datasets—such as scalability, distributed computing, and the need to adapt algorithms for large-scale processing.

A practical foundation for building scalable machine learning solutions using PySpark ML in big data environments. The content focuses on designing and implementing end-to-end machine learning pipelines with transformers and estimators, while developing regression, classification, and clustering models that scale across distributed systems. Emphasis is placed on real-world implementation and informed platform selection for enterprise deployments using Azure Databricks, Microsoft Fabric, and Azure HDInsight, ensuring solutions are both technically robust and operationally viable at scale.

Large-scale text analytics introduces the challenges and techniques required to process and analyze unstructured text at enterprise scale using distributed computing frameworks. The focus is on applying natural language processing (NLP) techniques in scalable architectures to support text classification, sentiment analysis, and entity and relationship extraction across massive text corpora. Emphasis is placed on practical, production-oriented approaches for handling high-volume text data, with integration of Azure Cognitive Services to enhance accuracy, scalability, and operational efficiency in real-world analytics solutions.

Deep Learning for Big Data introduces the fundamentals of deep learning and advanced architectures specifically adapted for big data environments. Students will learn to implement neural networks for big data applications, apply transfer learning techniques with pre-trained models, and scale deep learning training across distributed clusters using modern frameworks and optimization techniques.

Generative AI and Big Data Integration explores how generative AI transforms big data analytics by enabling intelligent, natural language–driven workflows at scale. You will learn how foundation models and large language models integrate with distributed data pipelines to automate insights, enhance analytics, and power modern data applications. Through hands-on labs, you will implement LLM integration, apply fine-tuning for domain-specific use cases, and design production-ready GenAI solutions for real-world big data scenarios.
