Your examples are correct. I am not sure how you identify variables internally, but I would rather make Hermicity inherent to the variable, and not defined through identities. So, given...

Sometimes yes, but in a very special way, so I think your separation will work just fine. The only case when I need some kind of mixing is when we...

This sounds perfect!

See the conda recipes for [xgboost](https://github.com/conda-forge/xgboost-feedstock/tree/master/recipe) and [lightgbm](https://github.com/conda-forge/lightgbm-feedstock/tree/master/recipe) for hints.

Clang now compiles the problem without problems both on Linux and macOS. The CUDA part remains to be checked,

Thanks. I swear this question came up before, but I can't find it. You can use `get_surface_state` to get the activation map for a given set of data instances (or...

Not sure about this. The calculation is definitely not right for the toroid surface, which should have a higher quality embedding. I also tried PCA initialization. That significantly improves the...

This is really weird. Normally I set the epochs much lower (around 10), and the map larger, but it further increases the topographic error. I am really puzzled by this....

That is the lattice. I tried to reduce the problem on a toy problem on a rectangular lattice. What I noticed is that there is a strong competition to be...

Thanks. I welcome all contributions, of course. I know that in theory, hexagonal grids are more advantageous, but in practice, I've never seen any tangible difference. So the hexagonal grid...
