Summary There has been tremendous advancement in commercial applications recently using the Big Data, Deep Analytics including machine learning (ML) and artificial intelligence (AI) methods. These methods also provide emerging technologies to address the unique challenges in the Common Tactical Air Pictures (CTAP) and Combat Identification (CID) applications. It is also imperative to test and adapt commercially available tools now to meet the ongoing needs and requirements for the Common Tactical Air Pictures (CTAP) and Combat Identification (CID) requirements. In the past, we have been researching and testing on the Soar (Laird, 2012) cognitive architecture including reinforcement learning (RL) algorithm. One of the Soar advantages to start for the CTAP and CID application is that it is able to easily incorporate existing English like production rules. We also use a data-driven lexica link analysis (LLA) to initialize/discover new rules for the Soar-RL. The explainable characteristics of Soar-RL is a very important feature for CID, where the decision rules are presented for each reasoning. In this project, we will work the DARPA XAI community to design, improve and implement the XAI feature of the Soar-RL for a better human-machine interface, explanation and cognitive architecture that address and improve the cognitive CID.
