comment How should I enter indexed terms? For example, constants $n_k$ for $k\in\{1,\,\ldots,\,N\}$
Could you mind explaining the new functionality Indexed a bit more in details. What does it return just formatted text ... Can we assign values to Indexed what is the difference between part and Indexed etc. It will be very helpful for future users.

comment Managing Stack Exchange favorites via Documentation Center
@Kuba In an ideal situation, I would like to see this question favorited under documentation 'ref/Notebook' due to the keywords used. May be as a separate section simmilar to 'Detailed' section. However, as Timothy mentioned it may be very hard to edit Doc Center. But, may be it's easier to replicate the doc structure of Mathematica in an other gui or cell and associated and structure the favorites with this new gui.

comment How can I train a binary classifier to find a logo?
@M.R did you check the link its explained step by step in the 2. Answer. There's also other related links there. Dont expect 90 persent accuracy. 80 isreasonable result.

comment How can I train a binary classifier to find a logo?
You may check this answer. Mainly, you may create codebook+histogram explained in stackoverflow.com/questions/19048891/… Also, you may use ImageKeypoints with option "Descriptor" with surf descriptor instead of sift.

comment Is there a way to show some “weighted” residuals after LinearModelFit?
you may try Rescale. something like: data = {{0, 1}, {1, 0.05}, {3, 2}, {5, 4}}; dat=Rescale[data, {-0.5, 0.5}] lm = LinearModelFit[dat, x, x]; lm["FitResiduals"]

I think Euclidean distance is not right measure for distributions. you may check en.wikipedia.org/wiki/Statistical_distance

comment Calculating a potential function using the finite element method
@MarkMcClure yes you are right. It is also mentioned in other discussions that some parameters are ignored. However, by discretizing region as in Q 3 {0, 0} problem disappears.

comment Calculating a potential function using the finite element method
problem 2 and 3 can be corrected by using DiscretizeRegion. dis = DiscretizeRegion[reg] and than mesh = ToElementMesh[dis, MaxCellMeasure -> 0.0005, "MaxBoundaryCellMeasure" -> 0.01];

comment Object separation from a 2.5D surface
@zeckra Instead of dealing with geometric models how about defining problem as optimization task and fitting biggest blob or sphere? If I am not mistaken MichaelE2 has related nice solution for 2d circle.

comment Proving (self) similarity with Mathematica - Reccurrence Plots, Similarity Plots etc
May be you can use fractal dimensions to measure the similarities. Also related post might help 'Measuring fractal dimension of natural objects from digital images' but mainly for images mathematica.stackexchange.com/questions/13125/…

comment Strange behavior of `BoundaryMeshRegion`
I also think it a bug. An easy way to achieve the same result is with r = BoundaryDiscretizeRegion[Cuboid[{4, 4, 4}, {6, 6, 6}]]

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard Programming wise yes there are many flexibilities in Mathematica and hard to map one by one. However, toolboxes such as image possessing, statistics, wavelets, ect. has very similar commands. It may need a lot of effort to map, but as community page one can improve and add thing as common effort. I personally think it will be quite beneficial for future 2 program users.
