For a multitude of tasks that come naturally to humans, performance of AI systems is inferior to human level performance. We show how human intellect made available via crowdsourcing can be used to complement an existing system during execution. We introduce a hybrid workflow that queries people to verify and correct the output of the system and present a simulation-based workflow optimization method to balance the cost of human input with the expected improvement in performance. Through empirical evaluations on an image captioning system, we show that the hybrid system, which combines the AI system with human input, significantly outperforms the automated system by properly trading off the cost of human input with expected benefit. Finally, we show that human input collected at execution time can be used to teach the system about its errors and limitations.
Anyone want to take a crack at explaining what they do and how well it works?
