Of course not. psnr is a measure of how close two images are to each other, not an overall assessment of which image is "better".
It doesn't help to report a P value unless you clearly state what test was used to compute it. Asterisks? Many people add asterisks to tables and graphs to show how low the P value is. The standards for one to three asterisks are quite standard (<0.05, <0.01, <0.001), and both th...

We have theConfusion Matrixto deal with and evaluate Classification algorithms. While R square is an important error metric to evaluate the predictions made by a regression algorithm. R squared (R2)is a regression error metric that justifies the performance of the model. It represents the value o...

Auto-compute p-value label positions using the functionadd_xy_position()[in rstatix package]. Add the p-values to the plot using the functionstat_pvalue_manual()[in ggpubr package]. The following key options are illustrated in some of the examples: ...
confident that you know what that true proportion is. These confidence interval techniques can be applied to find the exact confidence interval of a mean in R, calculate confidence interval from a p value, or even compute an exact confidence interval for variance in R from a sampling ...
In PyTorch, these refer to implementations that accept different input arguments (but compute the same thing). This is summarized below. PyTorch Loss-Input Confusion (Cheatsheet) torch.nn.functional.binary_cross_entropy takes logistic sigmoid values as inputs torch.nn.functional.binary_cross_entropy_...
Evaluating portfolios: In addition to computing the percentage changes of individual assets within a portfolio, investors can compute the change for their entire portfolio. This can be useful in determining whether their currentasset allocationis delivering the returns they need or whether they should ...
While the mathematics behind these models can be complex, investors don't need to do the calculations manually. Many trading platforms and online tools can quickly compute option prices based on them. While theBlack-Scholesmodel remains the foundation of options pricing, there's a trend toward ev...
