The ever-growing artificial intelligence (AI) applications have greatly reshaped our world in many areas, e.g., smart home, computer vision, natural language processing, etc. Behind these are usually machine learning (ML) models with extremely large size, which require huge data sets for accurate training to mine the value contained big data. Large ML models, however, can consume tremendous computing resources achieve decent performance and thus, it is difficult train them...

Real-time video perception tasks are often challenging on resource-constrained edge devices due to the issues of accuracy drop and hardware overhead, where saving computations is key performance improvement. Existing methods either rely domain-specific neural chips or priorly searched models, which require specialized optimization according different task properties. These limitations motivate us design a general task-independent methodology, called <i>Patch Automatic Skip Scheme</i> (PASS),...

One non-negligible flaw of the convolutional neural networks (CNNs) based single image super-resolution (SISR) models is that most them are not able to restore high-resolution (HR) images containing sufficient high-frequency information. Worse still, as depth CNNs increases, training easily suffers from vanishing gradients. These problems hinder effectiveness in SISR. In this paper, we propose Dual-view Attention Networks alleviate these for Specifically, local aware (LA) and global (GA)...

Over the past few years, edge learning has achieved significant success in mobile networks. Few works have designed incentive mechanism that motivates nodes to participate learning. However, most existing only consider myopic optimization and assume all are honest, which lacks long-term sustainability final performance assurance. In this paper, we propose Chiron, an incentive-driven Byzantine-resistant based on hierarchical reinforcement (HRL). First, our goal includes both...

Iteration based collaborative learning (CL) paradigms, such as federated (FL) and split (SL), faces challenges in training neural models over the rapidly growing yet resource-constrained edge devices. Such devices have difficulty accommodating a full-size large model for FL or affording an excessive waiting time mandatory synchronization step SL. To deal with challenge, we propose novel CL framework which adopts tree-aggregation structure adaptive partition ensemble strategy to achieve...

As to address the impact of heterogeneity in distributed Deep Learning (DL) systems, most previous approaches focus on prioritizing contribution fast workers and reducing involvement slow workers, incurring limitations workload imbalance computation inefficiency. We reveal that grouping into communities, an abstraction proposed by us, handling parameter synchronization community level can conquer these accelerate training convergence progress. The inspiration comes from our exploration prior...
