The network structure of the “BiLSTM+Dilated Convolution+3D Attention+CRF” model for CCNER Full size image The proposed deep learning-based CCNER module contains a four-layer bi-directional Long Short-Term Memory neural network (BiLSTM), bi-layer Dilated Convolution, a Self-Attention Layer, ...
To address these challenges, a fittings detection method based on the dynamic graph convolutional neural network (DGCNN) and U-shaped network (U-Net) is proposed, which combines three-dimensional detection with two-dimensional object detection. Firstly, the bi-level routing attention mechanism is ...
This work aims to call more attention to the adversarial and defensive aspects of UAV target detection models. Keywords: unmanned aerial vehicle (UAV); dynamicbi-level integrated attack (DBI-Attack); black box; mislabeling attack; fabrication attack...
Figure 3. Structure of word-level attention. The word embedding ℎ𝑖𝑡hit is sequentially put into a neural network BiLSTM, 𝛼𝑖𝑡αit are weights for ℎ𝑖𝑡hit, and 𝑆𝑖Si is the sentence vector computed by weighting words. 3.1...
,αℎ𝑣ℎ)𝑊𝑂 where ℎ is the number of attention heads, and 𝑊𝑂 is the weight matrix used to map the concatenated attention heads to the output dimension. Concat denotes the concatenation of vectors. The multi-head attention mechanism can focus on different parts of the input...
Research on automated health monitoring of tunnel structures has received significant attention in recent years, as recorded in [3,4]. Various solutions that deal with different aspects of automated tunnel inspection were proposed through the use of cost-effective photographic equipment and computer visi...
