Machine learning (ML) pipeline architecture design patterns are essential for transforming raw data into predictions by creating structured, modular systems that accommodate scalability, adaptability, and maintainability. The blog explores various design patterns, such as Single Leader Architecture and Directed Acyclic Graphs (DAG), which facilitate efficient task execution and dependency management. It also discusses advanced concepts like data parallelism and model parallelism, which optimize resource usage in large-scale models, and federated learning, which prioritizes data privacy. Real-world examples from companies like Netflix and Facebook illustrate the application of these patterns in managing ML workflows and optimizing training processes. While these architectures enhance efficiency and scalability, they also present challenges like potential bottlenecks and complexity in implementation. The blog emphasizes the importance of understanding these patterns to build robust, flexible ML systems that are easy to troubleshoot and adapt to changing requirements.
