How to Build Machine Learning Models for Deployment

TL;DR

To effectively deploy machine learning models, start by collecting a development set that mirrors real-world scenarios and clearly define an evaluation metric. This ensures your model's performance is aligned with production goals. Additionally, consider automated labeling strategies to gather sufficient training data efficiently, while keeping in mind the importance of accurate labeling to avoid bias and distribution mismatches.
