它的Image Encoder采用的是VGG19和Resnet152,Text encoder采用的是GRU。两个Encoder输出的特征经过线性层映射到同一个联合语义空间后,采用cosine similarity计算图文相似度。它的主要贡献是:提出在训练阶段使用hardest negative triplet loss,即:只考虑mini batch中和目标最相似的样本的计算triplet loss,而不是目标样本之外...
同理,判别器的loss定义为 Deep Attentional Multimodal Similarity Model DAMSM学习了两个神经网络(text encoder-LSTM,image encoder -CNN),将图像的子区域和句子中的词映射到同一个语义空间来计算相似度,在训练生成器的时候就可以通过计算img-text similarity得到一个fine-grained loss The text encoder 文本编码器是...
作者提出了两个模块,相似图推理(SGR: Similarity Graph Reasoning)和相似注意力过滤(SAF: Similarity Attention Filteration)。前者用于识别单词图片相似性之间的复杂关系,后者用于过滤一些非重要的单词以提高预测准确性。 两个新模块 首先,作者延续之前的文章方法(Anderson et al. 2018)使用 Faster R-CNN 在图片中提取...
Through establishment of a test set including four languages, an identification effect of the text-image similarity-degree measurement method is tested and by application of recall ratio, precision ratio and an F value, an effect of the method is measured and a result turns out that the recall...
In this paper, we present Stacked Cross Attention to discover the full latent alignments using both image regions and words in a sentence as context and infer image-text similarity. Our approach achieves the state-of-the-art results on the MS-COCO and Flickr30K datasets. On Flickr30K, our ...
Learning cross-modality similarity for multinomial data Many applications involve multiple-modalities such as text and images that describe the problem of interest. In order to leverage the information present i... Y Jia,M Salzmann,T Darrell - IEEE International Conference on Computer Vision 被引量...
