After training a model in Amazon SageMaker, the next question is how to actually use it. This is where many people get stuck. SageMaker offers multiple ways to run inference, and it’s not always obvious which one to choose. In this guide, I’ll explain the differences between real-time, batch, and serverless inference using simple examples. […]
If you’re learning machine learning on AWS – or just want to understand how models work without writing code, this is one of the simplest workflows to try. In this post, I’ll walk through how I built a loan approval prediction model using SageMaker Canvas, and where this kind of workflow shows up in AWS […]
This guide walks through real training and validation loss behavior in Amazon SageMaker using XGBoost, helping you understand overfitting with a practical example. When you train a machine learning model in Amazon SageMaker, the first thing you usually look at is the loss. If it’s going down, it feels like everything is working. But that’s […]
If you’ve spent any time learning machine learning or preparing for the AWS Certified Machine Learning – Associate (MLA-C01) exam, you’ve probably run into this situation: Your model shows 90% accuracy. Everything looks solid… but something feels off. That’s usually the moment you realize accuracy isn’t telling the full story. This is where precision, recall, […]
