Artem Sokolov

I am a research scientist at Amazon Berlin working on machine translation and other structured prediction problems for NLP. Simultaneously, I hold an Honorary Professor position at the Heidelberg University.

Before joining Amazon I was a postdoc at the Statistical NLP Group, lead by Prof. Stefan Riezler, and earlier at the LIMSI and the Orange Labs, R&D in France. I obtained a PhD in Computer Science and Artificial Intelligence from the IRTCITS research center in Kyiv for a thesis on randomized representations for locality-sensitive sequence embeddings.
