Background

Jurka is best known for developing the artificial intelligence that ranks the LinkedIn news feed.[1][2] Previously, Jurka developed machine learning algorithms for news recommendations in the Pulse news reading application, which was acquired by LinkedIn in 2013.[3][4]

As a Ph.D. student at UC Davis, Jurka collaborated on numerous projects in political science spanning media framing,[5][6] civic engagement,[7] and tobacco and immunization policy.[8] Additionally, he wrote text classification software, including RTextTools and MaxEnt for the R statistical programming language,[9][10][11][12] both of which have since been deprecated.[13][14]

He is the son of computational biologist Jerzy Jurka.[15]

gollark: rustc is quite slow. ghc, however, is fairly fast. The implications are obvious.
gollark: rustc is to be rewritten in Haskell for greater performance.
gollark: Wondrous.
gollark: Ugh, icecast is being highly apioformic wrt. metadata.
gollark: No, the correct format is HH-dd-ss.
