Secure semantic optical communication scheme based on the multi-head attention mechanism

2023 · Optics Letters

In this paper, an artificial-intelligence-based secure semantic optical communication scheme is proposed. The semantic features of the original text information are extracted using Transformer. Compared with other networks, Transformer reduces the complexity of the structure …

QCA-Net: Quantum-based Channel Attention for Deep Neural Networks

2023

The channel attention mechanism, which adaptively recalibrates each channel's weight, can enhance the performance of deep neural networks. Most channel attention modules use simple pooling operations to aggregate spatial information. The drawback is the incapability …

Segmentation-aware relational graph convolutional network with multi-layer CRF for nested named entity recognition

2024 · Complex & Intelligent Systems

Abstract Named Entity Recognition (NER) is fundamental in natural language processing, involving identifying entity spans and types within a sentence. Nested NER contains other entities, which pose a significant challenge, especially pronounced in the domain …
