2). The probability of the predictions is computed by taking the Softmax of the vector similarity between the feature vector zi and the prototype vectors C (Eq. 3).(1)L(zi1,zi2)=l(zi1,qi2)+l(zi2,qi1)(2)l(zi,qi)=-∑kqi(k)logpi(k)(3)wherepi(k)=exp(ziTck/τ)∑k′exp...
Numerically, we evaluated the denoising performance based on structural similarity (SSIM)48 and peak signal-to-noise ratio (PSNR) $$\begin{aligned} \textrm{PSNR}(Y,A) = 10\cdot \log _{10} \left( \frac{R^2}{\textrm{MSE}(Y,A)}\right) [dB] \end{aligned}$$ (2) where \(Y\)...
We show that simple patch-based models, such as epitomes, can have superior performance to the current state of the art in semantic segmentation and label super-resolution, which uses deep convolutional neural networks. We derive a new training algorithm for epitomes which allows, for the first...
For evaluation purposes, the metrics MSE, peak signal-to-noise ratio (PSNR) and structural similarity index measure (SSIM) were calculated in 2D and and subsequently averaged across all test slices. The quantitative results are presented in Table 1. Although the network trained with SURE loss ...
Furthermore, we integrate SS-Attention into the blind-spot network called self-similarity-based blind-spot network (SS-BSN). We conduct the experiments on real-world image denoising tasks. The proposed method quantitatively and qualitatively outperforms state-of-the-art methods in self-supervised ...
Self-similarity and Reynolds number invariance in Froude modelling This review aims to improve the reliability of Froude modelling in fluid flows where both the Froude number and Reynolds number are a priori relevant. Two ... V Heller - 《Journal of Hydraulic Research》 被引量: 9发表: 2016年...
Based on the weaknesses of contrastive learning using negatives, we introduce a self-supervised soft contrastive learning approach called Similarity Contrastive Estimation (SCE) that contrasts positive pairs with other instances and leverages the push of negatives using the inter-instance similarities. Our...
The spectrum of stage 3 of reaction showed notable similarity with iso-hexanes (Fig. 5d,e), confirming the efficient transformation of HDPE into iso-alkanes. A full catalytic circle can be established (Fig. 5f). Upon adsorption on the LSP zeolite, PE is activated via hydride abstraction38,...
