This repository contains code for setting up the GuessWhich Game along with Amazon Mechinical Turk (AMT) integration for real time data collection. The data collection settings can be changed easily by modifying certain configurations defined here.

Abstract

As AI continues to advance, human-AI teams are inevitable. However, progress in AI is routinely measured in isolation, without a human in the loop. It is important to measure how progress in AI translates to humans being able to accomplish tasks better; i.e., the performance of human-AI teams. In this work, we design a cooperative game – GuessWhich to measure human-AI team performance in the specific context of the AI being a visual conversational agent. The AI, which we call ALICE, is provided an image which is unseen by the human. The human then asks ALICE questions aboutthis secret image to identify it from a fixed pool of images.

We measure performance of the human-ALICE team by the number of guesses it takes the human to correctly identify the secret image after a fixed number of dialog rounds with ALICE. We compare performance of the human-ALICE teams for two versions of ALICE. While AI literature shows that one version outperforms the other when paired with another AI, we find that this improvement in AI-AI performance does not translate to improved human-AI performance.
