arpack_wrapper.hpp handles non self-adjoint input ?

Hey, you're right the matrix has to be self-adjoint. Isomap should produce self-adjoint matrix as well so I will have to check what's going on there.

arpack_wrapper.hpp handles non self-adjoint input ?

I can reproduce some asymmetry in isomap matrix, will let you know what caused that

arpack_wrapper.hpp handles non self-adjoint input ?

@coderlevi thanks for researching on that. You are right, it was somehow missed that neighborhood matrix (hence, the shortest path matrix) is not symmetrical. I think it makes sense to...

arpack_wrapper.hpp handles non self-adjoint input ?

I'd keep it open until I or someone else merge some code fixing that

The neighborhood graph is not connected

Hey! Sorry it took a while to respond you. The problem is that the neighborhood strategy being used in Tapkee is dead simple: it finds the nearest neighbors for each...

Aliasing error during eigen decomposition

Hey, thanks for the report. It seems to be an actual bug. The `eval` thing resolves that indeed but it would bump the memory usage 2x for a moment. Let...

Aliasing error during eigen decomposition

It seems that eval should be here. I just added it in ec3514033c036795ca819d3ac68b61a58d24ac53

Implement streaming mode for landmark based algorithms

Asked @karlnapf about that and apparently good idea is to collect feature vectors until solution stabilizes

ezoptionparser error

Completely lost it! So sorry about that. Is it still relevant?

Compile failed with OpenMP on Windows

Thanks for reporting! I am not sure what caused this error yet. Have you tried other versions of eigen?
