SUMMARY

Data labeling at scale is a complicated endeavor involving operations, machine learning and game theory. In this talk we focus on the game theory, and introduce a model of human-in-the-loop labeling as an optimization problem. Based on our (Scale AI’s) experience of operating tens of thousands of labelers on high complexity tasks, we will discuss how various problems predicted by the model map to observed results.
