Abstract On-device Artificial Intelligence (AI) accelerators capable of not only inference but also training neural network models are in increasing demand in the industrial AI field, where frequent retraining is crucial due to frequent production changes. Batch normalization (BN) is fundamental to training convolutional neural networks (CNNs), but its implementation in compact accelerator chips remains challenging due to computational complexity, particularly in calculating statistical parameters and gradients across mini-batches. Existing accelerator architectures either compromise the training accuracy of CNNs through approximations or require substantial computational resources, limiting their practical deployment. We present a hardware-optimized BN accelerator… More >

Abstract Acoustic scene classification (ASC) is a method of recognizing and classifying environments that employ acoustic signals. Various ASC approaches based on deep learning have been developed, with convolutional neural networks (CNNs) proving to be the most reliable and commonly utilized in ASC systems due to their suitability for constructing lightweight models. When using ASC systems in the real world, model complexity and device robustness are essential considerations. In this paper, we propose a two-pass mobile network for low-complexity classification of the acoustic scene, named TP-MobNet. With inverse residuals and linear bottlenecks, TP-MobNet is based on… More >

Abstract Energy efficiency (EE) is a critical design when taking into account circuit power consumption (CPC) in fifth-generation cellular networks. These problems arise because of the increasing number of antennas in massive multiple-input multiple-output (MIMO) systems, attributable to inter-cell interference for channel state information. Apart from that, a higher number of radio frequency (RF) chains at the base station and active users consume more power due to the processing activities in digital-to-analogue converters and power amplifiers. Therefore, antenna selection, user selection, optimal transmission power, and pilot reuse power are important aspects in improving energy efficiency in… More >
