ML.NET Model Lifecycle: Retraining and Saving Models in C#

Static machine learning models quickly become outdated as real-world data changes. To maintain high accuracy in production, you must know how to continuously update your models with fresh information. This text-based course guides you through the entire process of retraining and saving ML.NET models using C# code. You will learn how to load existing models, feed them new training data, and serialize the updated models back to disk for seamless deployment. What you'll learn: - Understand the core concepts of the ML.NET model lifecycle and pipeline architecture. - Load pre-trained models and prepare new dataset pipelines for retraining. - Retrain classification models using the ML.NET core library. - Save and serialize updated models to file systems for production deployment. - Apply retraining techniques to practical sentiment analysis classification tasks. - Implement best practices for managing model versions and updating prediction engines. You will start with the foundational concepts of model persistence and pipeline design in ML.NET. From there, you will progress through step-by-step written explanations and practical C# code snippets that demonstrate how to load, retrain, evaluate, and save your models. This course is designed for .NET developers who are new to machine learning or want to understand the operational side of ML.NET. A basic familiarity with C# is recommended, but no prior machine learning experience is required. Start learning today to build adaptable, production-ready machine learning applications in the .NET ecosystem.
