Summary

In this chapter, we explored various programmatic labeling techniques in machine learning. Labeling data is essential for training effective models, and manual labeling can be time-consuming and expensive. Programmatic labeling offers automated ways to assign meaningful categories or classes to instances of data. We discussed a range of techniques, including pattern matching, DB lookup, Boolean flags, weak supervision, semi-weak supervision, slicing functions, active learning, transfer learning, and semi-supervised learning.

Each technique offers unique benefits and considerations based on the nature of the data and the specific labeling requirements. By leveraging these techniques, practitioners can streamline the labeling process, reduce manual effort, and train effective models using large amounts of labeled or weakly labeled data. Understanding and utilizing programmatic labeling techniques are crucial for building robust and scalable machine learning systems.
