摘要:

随着对地观测需求的不断增长,提供可靠的实时遥感推理服务以满足低延迟要求至关重要。空间算力网络(Space-CPN)通过提供星上计算能力和广覆盖特性,为实时推理提供了极具前景的解决方案。本文提出了一种面向低轨卫星星座的遥感人工智能应用部署框架,旨在实现实时推理性能。该框架采用微服务架构,将单体推理任务分解为可复用的独立模块,以解决高延迟与资源异构性问题。这种分布式方法可实现微服务的优化部署,在满足服务质量与功能需求的同时最小化资源利用率。我们在部署问题中引入鲁棒优化,以应对数据不确定性。此外,我们将该鲁棒优化问题建模为部分可观测马尔可夫决策过程,并提出一种鲁棒强化学习算法来处理半无限服务质量约束。我们的方法可得到次优解,在保持可接受计算成本的同时最小化精度损失。仿真结果验证了该框架的有效性。

英文摘要:

With the growing demand for Earth observation, it is important to provide reliable real-time remote sensing inference services to meet the low-latency requirements. The Space Computing Power Network (Space-CPN) offers a promising solution by providing onboard computing and extensive coverage capabilities for real-time inference. This paper presents a remote sensing artificial intelligence applications deployment framework designed for Low Earth Orbit satellite constellations to achieve real-time inference performance. The framework employs the microservice architecture, decomposing monolithic inference tasks into reusable, independent modules to address high latency and resource heterogeneity. This distributed approach enables optimized microservice deployment, minimizing resource utilization while meeting quality of service and functional requirements. We introduce Robust Optimization to the deployment problem to address data uncertainty. Additionally, we model the Robust Optimization problem as a Partially Observable Markov Decision Process and propose a robust reinforcement learning algorithm to handle the semi-infinite Quality of Service constraints. Our approach yields sub-optimal solutions that minimize accuracy loss while maintaining acceptable computational costs. Simulation results demonstrate the effectiveness of our framework.
