AI Trustworthiness Challenges and Opportunities Related to IIoT Communicating this understanding can increase confidence in the system as part of the broader community context. AI decisions around physical actions such as controlling IoT actuators are not 100% predictable, yet trust based on evidence that they operate appropriately is needed. This is an argument for creating a model (e.g. digital twin) of a system, making it possible to test and simulate the operation of the system and anticipate outcomes. 14 It is difficult to trust a system that cannot be understood, such as a neural net system that makes decisions without providing a clear record of how decisions are reached. This has become a concern with systems used to automatically approve loans since such systems can have unintentional bias that could break laws, without being explicitly programmed to have such bias 11 12 . One approach that is being taken is to perform a sensitivity analysis by varying the inputs in a methodical manner to determine the behavior of the neural net to create evidence of how the system works. 13 T RUSTWORTHINESS OF AI S YSTEMS Trustworthiness of AI systems that learn requires that the data and approach used to train the system be trustworthy, as well as the system itself. 11 “Dangers of Human-Like Bias in Machine- Learning Algorithms”, May 2018, http://scholarsmine.mst.edu/cgi/viewcontent.cgi?article=1030&context=peer2peer 12 “ This is how AI bias really happens—and why it’s so hard to fix”, MIT Technology Review, https://www.technologyreview.com/s/612876/this-is-how-ai-bias-really-happensand-why-its-so-hard-to-fix/ 13 “Methods for Interpreting and Understanding Deep Neural Networks”, http://iphome.hhi.de/samek/pdf/MonDSP18.pdf 14 for example, see “Model-Based Engineering of Supervisory Controllers for Cyber-Physical Systems” in “Industrial Internet of Things, Cybermanufacturing Systems”, Springer, 2017 https://link.springer.com/chapter/10.1007/978-3-319-42559-7_5 IIC Journal of Innovation - 82 -
