IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe portability of Convolutional Neural Networks (ConvNets) on the mobile edge of the Internet has proven extremely challenging. Embedded CPUs commonly adopted on portable devices were designed and optimized for different kinds of applications, hence they suffer high latency when dealing with the parallel workload of ConvNets. Reduction techniques playing at the algorithmic level are viable options to improve performance, e.g. topology optimization using alternative forms of convolution and arithmetic relaxation via fixed-point quantization. However, their efficacy is hardware sensitive. This paper provides an overview of these issues using as a case study an image classification task implemented through open-source resources, namely different architectures of MobileNet (vl), scaled, trained and quantized for the ImageNet dataset. In this work, we quantify the accuracy-performance trade-off on a commercial board hosting an ARM Cortex-A big. LITTLE system-on-chip. Experimental results reveal mismatches which arise from the hardware.

| Abstract: | The portability of Convolutional Neural Networks (ConvNets) on the mobile edge of the Internet ha...s proven extremely challenging. Embedded CPUs commonly adopted on portable devices were designed and optimized for different kinds of applications, hence they suffer high latency when dealing with the parallel workload of ConvNets. Reduction techniques playing at the algorithmic level are viable options to improve performance, e.g. topology optimization using alternative forms of convolution and arithmetic relaxation via fixed-point quantization. However, their efficacy is hardware sensitive. This paper provides an overview of these issues using as a case study an image classification task implemented through open-source resources, namely different architectures of MobileNet (vl), scaled, trained and quantized for the ImageNet dataset. In this work, we quantify the accuracy-performance trade-off on a commercial board hosting an ARM Cortex-A big. LITTLE system-on-chip. Experimental results reveal mismatches which arise from the hardware. | |
