UnverifiedThe KLD of models uncensored via traditional full fine-tuning typically falls in the range of 0.1 to 0.5 or even higher, while LoRA-based methods generally fall between 0.05 and 0.15.63% similarUnverifiedThe +2 in the denominator of the HN ranking formula is a smoothing term that prevents new posts from receiving abnormally high scores due to an overly small denominator.59% similarUnverifiedThe key property of e-values is that if the null hypothesis H₀ is true, the expected value of the e-value does not exceed 1, which allows e-values to be safely multiplied sequentially to form a test martingale.59% similarUnverifiedIn MoE models, the weights of all experts still need to be loaded into VRAM on standby, so despite the computation being close to that of a 49B dense model, the VRAM footprint approaches the scale of the full 1T model.59% similarUnverifiedIn hypothesis testing, the null hypothesis H0 is set as β1=0, calculated through the t-statistic t = β1/SE(β1), and the p-value is then derived from the t-distribution.57% similar
