每一个模态 都提取出序列特征, 我们把这个seq 通过一个LSTM, 并且LSTM的 最后一个隐层接一个全连接映射到同一维度 2.1.2 Modality-Invariant and -Specific Representations 我们把同一个特征 映射到两个不同的特征空间中, 一个是模态不变特征, 一个是模态特有特征。 作者认为 模态不变 和 模态特有特征 提供了...
Moreover, our advanced dual-constrained triplet loss is introduced for better cross-modality matching performance. The experiments on two cross-modality person re-identification datasets show that MANN can effectively learn modality-invariant features and outperform state-of-the-art methods by a large ...
Meanwhile, for the individual part, a cross-modality triplet (CMT) loss was employed to distinguish the pedestrian images with different identities. Adversarial loss: Some works [60,63,68,81] also use adversarial learning to learn modality-invariant features. For example, [60,63] designed a ...

{C}\). The number of clustersCis output by DBSCAN65. Adaptive clustering allows the cell embedding to be separated between groups and compact within groups. The adaptive clustering loss reduces the correlation between the predicted logits (soft labels) of different types of clusters, thereby ...
1) which are sparse, scale- and rotation invariant, hence they are expected to perform well even with rigidly transformed or cropped queries. The BoW is defined on the features extracted from the CoMIRs of all the images in the searchable repository, by K-means clustering using a suitable ...
2. The guiding effect of self-supervision in the training process is rather beneficial when learning modality-invariant feature representations. Conclusion: In this article, we propose S2-Net, which introduces the self-supervised learning in the training learn the modality-invariant feature ...
Our solution can be considered a type of causal intervention: we first intervene VV by utilizing the perturbation strategy to create a new data distribution, which has never been observed in the original dataset; then, we enforce the prediction P(A|(Q, V))P(A|(Q, V)) to be invariant ...
In the context of orthogonal polynomials, a flat line can be considered a pure intercept and a ‘zero-order’ polynomial, in the sense that it exhibits zero changes in any direction. If the recurrence score was time-invariant, it would appear as a flat line indicating complete dominance of ...
Qin et al.25 use image disentanglement to decompose images into common domain-invariant latent shape features and domain-specific appearance features. Then the latent shape features of both modalities are used to train a regis- tration network. Arar et al.19 attempt to bypass the difficulties...
