Distributed Relay Selection for Heterogeneous UAV Communication Networks Using A Many-to-Many Matching Game Without Substitutability
This paper proposes a distributed multiple relay selection scheme to maximize
the satisfaction experiences of unmanned aerial vehicles (UAV) communication
networks. The multi-radio and multi-channel (MRMC) UAV communication system is
considered in this paper. One source UAV can select one or more relay radios,
and each relay radio can be shared by multiple source UAVs equally. Without the
center controller, source UAVs with heterogeneous requirements compete for
channels dominated by relay radios. In order to optimize the global
satisfaction performance, we model the UAV communication network as a
many-to-many matching market without substitutability. We design a potential
matching approach to address the optimization problem, in which the optimizing
of local matching process will lead to the improvement of global matching
results. Simulation results show that the proposed distributed matching
approach yields good matching performance of satisfaction, which is close to
the global optimum result. Moreover, the many-to-many potential matching
approach outperforms existing schemes sufficiently in terms of global
satisfaction within a reasonable convergence time.Comment: 6 pages, 4 figures, conferenc
ToMChallenges: A Principle-Guided Dataset and Diverse Evaluation Tasks for Exploring Theory of Mind
Theory of Mind (ToM), the capacity to comprehend the mental states of
distinct individuals, is essential for numerous practical applications. With
the development of large language models, there is a heated debate about
whether they are able to perform ToM tasks. Previous studies have used
different tasks and prompts to test the ToM on large language models and the
results are inconsistent: some studies asserted these models are capable of
exhibiting ToM, while others suggest the opposite. In this study, We present
ToMChallenges, a dataset for comprehensively evaluating Theory of Mind based on
Sally-Anne and Smarties tests. We created 30 variations of each test (e.g.,
changing the person's name, location, and items). For each variation, we test
the model's understanding of different aspects: reality, belief, 1st order
belief, and 2nd order belief. We adapt our data for various tasks by creating
unique prompts tailored for each task category: Fill-in-the-Blank, Multiple
Choice, True/False, Chain-of-Thought True/False, Question Answering, and Text
Completion. If the model has a robust ToM, it should be able to achieve good
performance for different prompts across different tests. We evaluated two
GPT-3.5 models, text-davinci-003 and gpt-3.5-turbo-0301, with our datasets. Our
results indicate that consistent performance in ToM tasks remains a challenge.Comment: work in progres
