In particular, MAPS actively selects which of the oracles to imitate and improve their value function estimates, and MAPS-SE additionally leverages an active state exploration criterion to determine which state one should explore.

MAPS and MAPS-SE, which stand for Max-aggregation Active Policy Selection with Active State Exploration, are classes of policy improvement algorithms that perform imitation learning from multiple suboptimal oracles.

How can an agent actively learn from multiple blackbox oracles by taking advantage of their complementary expertise to learn a better policy in a sample-efficient manner? In our #ICML2023 paper, we introduce MAPS (Active Policy Selection) and MAPS-SE (+Active State Exploration)
