FOR IMMEDIATE RELEASE No. 3358

TOKYO, June 3, 2020 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed a cooperative artificial intelligence (AI) technology that enhances work collaboration between humans and machines by using inverse reinforcement learning (IRL) to learn and imitate the actions of skilled workers. IRL, one of the key features of Mitsubishi Electric's Maisart^®* AI technology, enables machines to imitate human-like actions based on relatively small amounts of data. The new cooperative AI technology will be further refined through test deployment in automated guided vehicles (AGVs) and robots at production and distribution sites where machines operate alongside humans. Eventually, the technology is expected to be used in autonomous driving vehicles and other applications.

Key Features

1. 1)Improves efficiency in environments where both humans and machines work

   In mixed-work environments populated with humans and machines, Mitsubishi Electric's collaborative AI technology enables AGVs to use images from video recordings of these work areas to learn and imitate the actions of humans. By learning actions such as yielding, the technology helps AGVs to avoid unwanted situations such as collisions or stalemates. In-house simulations conducted by Mitsubishi Electric raised operational efficiency by about 30 percent compared to operations in conventional mixed-work environments populated with less intelligent machines.

2. 2)Maisart's IRL reduces amount of operational data required for learning

   To enable AI to learn and imitate human actions, conventional machine learning requires huge amounts of operational data -in this case video data- which incurs time and cost burdens. Mitsubishi Electric's Maisart AI, however, uses IRL to reduce the amount of data required to learn and imitate human actions. In simulations, the new technology required only 10 percent or less video data used normally.

Future Development

Going forward, Mitsubishi Electric will continue to develop its new cooperative AI for eventual application in commercial facilities. The envisioned benefits include improved operational efficiency, enabling workers to maintain social distancing and allowing machines and humans to operate alongside each other safely in settings such as factory production lines and logistics warehouses as well as in applications for autonomous-driving vehicles.
