Data Preprocessing Guide for Beginners in ML

Before machine learning (ML) models can generate predictions or insights, the raw data must first be cleaned, organized, and transformed into a suitable format for the model. This process is known as data preprocessing. It is the foundation of every successful ML project. It ensures that the model learns from high-quality, consistent, and well-structured input rather than noisy, incomplete, or biased information. In this hands-on guide, we’ll walk through how to transform a raw [...]

Amazon Bedrock + Promptfoo: Rethinking LLM Evaluation Methods

I discovered something embarrasing about my LLM development workflow last month.
