AdjustSmoothL1Loss substracts two variables with different quantities

❓ Questions and Help

I'm confused by the AdjustSmoothL1Loss using running_mean-running_var in the paper. Running mean and running_var have different dimensional quantity. Subtracting has no meaning on them.

e.g., if running_mean stands for meter, then running_var is m^2 according to Dimensional analysis

Only commensurable quantities (physical quantities having the same dimension) may be compared, equated, added, or subtracted.

Maybe use standard deviation?
