ICSICT 2022: A Video-based Fall Detection Network by Spatio-temporal Joint-point Model on Edge Devices

Traditional neural networks deployed on CPU/GPU architectures have achieved impressive results on various AI tasks. However, the growing model sizes and intensive computation have presented stringent challenges for deployment on edge devices with restrictive compute and storage resources. This paper proposes a one-shot training-evaluation framework to solve the neural architecture search (NAS) problem for in-memory computing, targeting the emerging resistive random-access memory (RRAM) analog AI platform. We test inference accuracy and hardware performance of subnets sampled in different dimensions of a pretrained supernet. Experiments show that the proposed one-shot hardware-aware NAS (HW-NAS) framework can effectively explore the Pareto front considering both accuracy and hardware performance, and generate more optimal models via morphing a standard backbone model.
