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"]

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];
