2022 was the inaugural year of the Institute for Artificial Intelligence and Data Science (IAD) Distinguished Speaker Series. Each year we bring some of the nation's most prominent researchers and innovators from academia, government, and industry to speak on topics of interest to the artificial intelligence, computational science, and data science community in Buffalo.
Distributed inference when the participants are only machines or electronic devices, e.g., sensors, has been explored extensively in the signal processing and machine learning literature. However, there are fundamental differences between such rational systems and systems where the agents include humans due to their cognitive limitations, imperfect rationality as well as behavioral uncertainties. In information fusion systems that include humans, modeling and analysis need to take several factors into account, including cognitive biases of humans, mechanisms to handle uncertainties and noise, and unpredictability of humans, in contrast to inference processes consisting of only machine agents.
In this talk, we discuss aspects of human-sensor networks by focusing on specific problems, including collaborative human decision-making with random local thresholds, decision fusion in integrated human-machine networks, prospect theoretic human decision-making in multi-agent systems, and portfolio theory-based resource management. In each case, we aim to optimize the system performance based on appropriate modeling of human behavior. We also summarize current challenges and research directions related to this problem domain.
