Most of the variables for Electron and Photon have been included into the class definition. We need to remove IdMaps from PhysObject definition.
We may keep a map inside TCEgamma though, but even the…

I just noticed that there's no mention of straightforward feature selection on the home page, which could fit under dimensionality reduction, or under preprocessing. Perhaps it should be mentioned wit…

In the [original paper](http://www-clmc.usc.edu/publications/T/tenenbaum-Science2000.pdf) you can see that it is possible not only to find a mapping
`Y = isomap.transform(X)`
but also the inverse …

I want to propose a major refactorization of viewer object/methods.
Currently if you use viewers you are basically dealing with (numpy) arrays, and passing these arrays to several functions (sim, si…

The core parts of manifold learning in {cluster_topics, isomap_topics, isomap_docs, gen_colors, plot_clusters} in `ldagibbsviewer.py` should be migrated to a new module `manifold.py`

I cloned and built the 'develop' branch today with `python_modular` on, and while the LMNN files appear to get built, and I can import `modshogun` without errors, `modshogun.LMNN` is not defined.
Thi…

Currently all similarity functions except `row_kld` returns similarities. But plotting methods (mds, isomap) require dissimilarities, and conversion from similarities to dissimilarities differ dependi…

I am unable to complete testing of scikit-learn I am getting 21 errors all seems related to the same thing and I have no clue how to solve this issue.
I am running Linux Gentoo distro and as far as I…

An S675 student pointed me out that to convert cosine similarity to dissimilarity one must use arccos(x), rather than 1-x. We are using dissimilarity matrices in isomap, so they need to be fixed.
