Human-in-the-loop machine learning: a state of the art

🤖 Plain-English Summary

Abstract Researchers are defining new types of interactions between humans and machine learning algorithms generically called human-in-the-loop machine learning. In this paper we review the state of the art of the techniques involved in the new forms of relationship between humans and ML algorithms.

🔑 Key Findings

• Depending on who is in control of the learning process, we can identify: active learning, in which the system remains in control; interactive machine learning, in which there is a closer interaction between users and learning systems; and machine teaching, where human domain experts have control over the learning process.
• Aside from control, humans can also be involved in the learning process in other ways.
• In curriculum learning human domain experts try to impose some structure on the examples presented to improve the learning; in explainable AI the focus is on the ability of the model to explain to humans why a given solution was chosen.
