Deep neural networks (DNNs) are successful in many computer vision tasks. However, the most accurate DNNs require millions of parameters and operations, making them energy, computation memory intensive. This impedes deployment large low-power devices with limited compute resources. Recent research improves DNN models by reducing requirement, energy consumption, number operations without significantly decreasing accuracy. paper surveys progress deep learning vision, specifically regards to...

Embedded devices are generally small, battery-powered computers with limited hardware resources. It is difficult to run deep neural networks (DNNs) on these devices, because DNNs perform millions of operations and consume significant amounts energy. Prior research has shown that a considerable number DNN’s memory accesses computation redundant when performing tasks like image classification. To reduce this redundancy thereby the energy consumption DNNs, we introduce Modular Neural Network...
