Contrastive Feature Loss for Image Prediction We provide a PyTorch implementation of our contrastive feature loss presented in: Contrastive Feature Loss for Image PredictionAlex Andonian,Taesung Park,Bryan Russell,Phillip Isola,Jun-Yan Zhu,Richard Zhang ...
Training supervised image synthesis models requires a critic to compare two images: the ground truth to the result. Yet, this basic functionality remains an open problem. A popular line of approaches uses the L1 (mean absolute error) loss, either in the pixel or the feature space of pretrained...

人眼能够快速辨别为正样本对），从而使得模型仍然能够通过学习部分低级特征来拟合最终的contrastive loss，影...
Occlusion prediction using the clutter feature β. Optimize camera parameters w.r.t loss. Repeat 2 to 5. NeMo的inference pipeline 实验我们follow了baseline的evaluation protocol,如下: 我们在Pacal3D+以及OccludedPascal3D+上进行测试了NeMo(L0为Pascal3D+,L1至L3为OccludedPacal3D+,并且随着level增加,物体被...
在对比学习中,本文采用了InfoNCE作为Contrastive Loss:\left[\mathcal{L}_U^1\right]^{c l}=\sum_{i \in \mathcal{U}}-\log \frac{\exp \left(\operatorname{sim}\left(\left[\mathcal{G}_U^{E P}\right]_{i \cdot},\left[\mathcal{G}_U^{F P}\right]_{i \cdot}\right) / \tau...
Additionally, contrastive loss has also been used to model inter-class dynamics in multimodal settings to enforce modality-agnostic feature representations with high semantic interpretability for multiple downstream tasks [391].

loss functions to produce task-specific or general-purpose representations. While it has originally enabled the success for vision tasks, recent years have seen a growing number of publications in contrastive NLP. This first line of works not only delivers promising performance improvements in various...
