SensorDrop: A Reinforcement Learning Framework for Communication Overhead Reduction on the Edge

no code implementations3 Oct 2019 Pooya Khandel, Amir Hossein Rassafi, Vahid Pourahmadi, Saeed Sharifian, Rong Zheng

As such decisions are application dependent and may change over time, they should be learned during the operation of the system, for that we propose a method based on Advantage Actor-Critic (A2C) reinforcement learning which gradually learns which sensor's data is cost-effective to be sent to the central node.

CacheNet: A Model Caching Framework for Deep Learning Inference on the Edge

no code implementations3 Jul 2020 Yihao Fang, Shervin Manzuri Shalmani, Rong Zheng

Inference of uncompressed large scale DNN models can only run in the cloud with extra communication latency back and forth between cloud and end devices, while compressed DNN models achieve real-time inference on end devices at the price of lower predictive accuracy.
