I work for Wolfram and oversee Wolfram Community. I am a physicist, Mathematica enthusiast and faculty member at Wolfram Science (NKS) Summer School. I am an author at the Wolfram Demonstration Project and sometimes write for Wolfram Blog. I enjoy creating applications and art with Mathematica, some can be found on my website. I also collecting Mathematica graphics at a Pinterest board and organized a video group Mathematica Render on Vimeo.


Comments & opinions expressed here are mine, and not those of my employer.

comment Compability between Graphics coordinates and shifted projections in GeoGraphics
@Kuba I am not that savvy in every field, could you please asks about deeper functionality on Wolfram Community? It is much easier to get a relevant developer to comment there. For example a recent thing that you know: community.wolfram.com/groups/-/m/t/427526

comment How can I train a binary classifier to find a logo?
@M.R. your training set is very small and not diverse. To have a more extended discussion you can try asking on community.wolfram.com where developers are hanging out - I am not really a specilist in the field.

comment Graph Coloring based on neighboring vertices? Cellular Automata
Very nice, +1, but is this "if there is a tie, the vertex keeps its current color" satisfied? Don't you just choose 1st color in the list of ties?

comment How can I train a binary classifier to find a logo?
@ybeltukov yes, I updated the code to show that. Got even better results - accidentally of course.
