High-density NAND flash memory, such as quadruple-level cell (QLC) flash, has has been widely adopted in emerging storage systems. However, its limited endurance and performance challenges necessitate novel solutions. Voltage-based write-once memory (WOM-v) codes have demonstrated their effectiveness in extending flash memory lifespan by reducing the erase count of flash blocks. Concurrently, secu...Show More
Nonnegative CANDECOMP/PARAFAC (CP) factorization of incomplete tensors is a powerful technique for finding meaningful and physically interpretable latent factor matrices to achieve nonnegative tensor completion. However, most existing nonnegative CP models rely on manually predefined tensor ranks, which introduces uncertainty and leads the models to overfit or underfit. Although the presence of CP...Show More
Secure two-party neural network (2P-NN) inference allows the server with a neural network model and the client with inputs to perform neural network inference without revealing their private data to each other. However, the state-of-the-art 2P-NN inference still suffers from large computation and communication overhead especially when used in ImageNet-scale deep neural networks. In this work, we d...Show More
The Sixth Generation (6G) networks are designed to provide ubiquitous, customized and intelligent services for users. Federated Learning (FL) as a privacy-preserving Artificial Intelligence (AI) paradigm is expected to be a key enabler for realizing ubiquitous distributed AI in 6G networks. Given this, this paper mainly focuses on FL in 6G, combining the advantages of both FL and 6G to provide a n...Show More
Deep learning provides an intelligent analytical approach for Big Data analysis and feature extraction in Industrial Internet of Things (IIoT).

Federated learning (FL) as a novel privacy-preserving deep learning paradigm break...Show More
The high memory footprint, high computational overhead and high power consumption of deep neural networks are the main bottlenecks in deploying network models to vehicular edge devices. Furthermore, in the collaborative learning process, the large number of training parameters can cause high communication overhead between the vehicular edge devices and the cloud. The redundant floating-point opera...Show More
Removing redundant parameters and computations before the model training has attracted a great interest as it can effectively reduce the storage space of the model, speed up the training and inference of the model, and save energy consumption during the running of the model. In addition, the simplification of deep neural network models can enable high-performance network models to be deployed to r...Show More
Based on the recent popularity of diffusion models, we have proposed a tensor-based diffusion model for 3D shape generation (TD3D). This generator is capable of tasks such as unconditional shape generation, shape completion and cross-modal shape generation. TD3D utilizes the Vector Quantized Variational Autoencoder (VQ-VAE) for encoding, compressing 3D shapes into compact latent representations, a...Show More
