Self-attention (SA) network has shown profound value in image captioning. In this paper, we improve SA from two aspects to promote the performance of image captioning. First, we propose Normalized Self-Attention (NSA), a reparameterization of SA that brings the benefits of normalization inside ...
An efficient self-attention mechanism, that is, cross-covariance attention, was utilized across our framework to perceive the correlations between points at different distances. Specifically, the transformer encoder extracts the target shape's local geometry details for identity attributes and the source...
Encoder由多头自注意力层(multi-headself-attention layer)与前馈神经网络(feed-forward network)组成,Decoder则由多头自注意力层、编码器解码器交叉注意力层和前馈神经网络构成。2.2 点代理NLP中的transformer以一个一维的单词嵌入序列作为输入,为了使三维点云适合于变压器,第一步是将点云转换为一系列向量序列。一个简...

解码器的几何感知结构和编码器一样,只是因为多了输入序列,因此对序列部分也要做一个几何感知,毕竟要整合两个 Attention: defforward(self,q,v,self_knn_index=None,cross_knn_index=None):norm_q=self.norm1(q)q_1=self.self_attn(norm_q)ifself_knn_indexisnotNone:knn_f=get_graph_feature(norm_q,se...
Besides, this model includes the two work modules: 1) a geometry gate-controlled self-attention refiner, for explicitly incorporating relative spatial information into image region representations in encoding steps, and 2) a group of position-LSTMs, for precisely informing the decoder of relative ...
Furthermore, we use a geometry-aware attention mechanism consisting of two feature attention modules to address the issue of self-occlusion in sparse view inputs, resulting in improved body shape details and reduced blurriness. Qualitative and quantitative results on the ZJU-MoCap and Thuman ...
