Hello,
Per Professor Bergmann's suggestion, I have implemented the first cut of a method to compute the Log function on the Stiefel manifold with the Submersion metric proposed in my paper [1].
I …

Brian Mckenna criticised current spec. He proposes to use FP approach to achieve much better modularity.
Suggest to read it, really good ideas with just three changes.

would you please list some references that give the detail about where the logarithmic map and exponential map come from?

你好,我注意到你在庞加莱圆盘模型上计算实体embedding时,论文中公式是:

这里说明embedding是在圆盘上面的,而你代码上面:

We should compile Sage with the extra compile argument `-march=native` for extra performance, at least if `SAGE_FAT_BINARY` is not set.
In `gcc/spkg_configure.ac` we check, whether the argument `-m…

这里的为啥直接加法了,我理解应该是用指数映射做加法
