Anagha Kulkarni, Sarath Sreedharan, Sarah Keren, Tathagata Chakraborti, David Smith, Subbarao Kambhampati
2020 arXiv   pre-print
This means that the robots need to be capable of generating behavior that aligns with human expectations and, when required, provide explanations to the humans in the loop.  ...  In addition, we explore the longitudinal aspect of explicable behavior and the trade-off that arises between the cost of design and the cost of generating explicable behavior over a time horizon.  ...  ACKNOWLEDGEMENTS The research of ASU contributors is supported in part by ONR grants N00014-16-1-2892, N00014-18-1-2442, N00014-18-1-2840, N00014-9-1-2119, AFOSR grant FA9550-18-1-0067, DARPA SAIL-ON grant  ...
