Some questions about statistics #4

Hi, @AdalbertoCq ,

Thanks for sharing a wonderful work!

I ran into some statistical problems about Cox proportional hazard regression while reading your work.

You mentioned in the article that you implement a central logarithmic transformation after using multiplicative replacement for WSI vector representations to ensure independence between the covariates. But I noticed that after these transformations, the sum of the features in each row is almost equal to 0. Whether this is a hidden linear relationship and affects the calculation of Cox covariates, such as making the value of a covariate tend to infinity?

I would be grateful if you could answer these questions to me.

Thanks.
