comment How to perform document classification (i.e. extracting topics from text)?
The following post mathematica.stackexchange.com/questions/47136/… discusses a seemingly unrelated problem that has, however, a similar solution. You can try the nonnegative matrix factorisation.

I think you made a mistake in defining the function. There are two different domains. Concerning the use of color, I do not think it conveys some additional information. I am for puristic style.

comment Artefacts in 3d plots
Thank you for your suggestions. MaxRecursion -> 12 and WorkingPrecision -> 22 is indeed an overkill. Besides, it does not remove the curve in x-y plane, it just makes it smooth. I wonder what is its origin?

@Bob Hanlon My PlotRange was chosen intensionally. I do prefer to have clipping.

I would like to comment on these suggestions and on the answer from @rhermans and Craig Carter. They are not satisfactory as they address only minor issues and do not solve the main problem of removing the curved line in the x-y plane.

comment Speed up Schwarz-Christoffel mapping
@ Chenminqi When I tried your solution on my machine I got incredible 1.4 sec! Combining your answer with the solution of @Simon Woods for the Schwarz-Cristoffel mapping I am getting 1.4 + 0.8 sec in total!

I learnt a lot from your answer. Even though your code was not the fastest for the ContourPlot I am accepting this answer because it gives an incredible boost was the second part -the Schwarz-Cristoffel transform. This was the slowest part of the code and now it runs in less than 1 sec!
