Network representation learning

In the last few years, thanks to the efforts of two PhDs under my super­vi­sion, Zekarias Kefato and Nasrullah Sheikh, I star­ted to explo­re pro­blems that are com­ple­te­ly outsi­de the distri­bu­ted systems topic: name­ly, machi­ne lear­ning with a par­ti­cu­lar focus on net­work repre­sen­ta­tion lear­ning. Maybe it is the aca­de­mic age, but when I say “I star­ted to explo­re” real­ly means Zekarias and Nasrullah are doing 95% of the work, and my role is just to make sure that the papers are easy to read.

We have star­ted to obtain some nice resul­ts, in the field of influen­cer detec­tion [MAISON17], casca­de pre­dic­tion [SNAMS18a] and net­work inference/link pre­dic­tion [MLG17] [MOD17] [Computing18] [LOD18][SNAMS18b]
