Lex Weaver,

an Australian computer scientist, since 2004 manager at the Australian Government, and before lecturer in the Department of Computer Science at the Australian National University, Canberra, Australia, where he already defended his B.Sc. and Ph.D. degrees in 1994 and 2003 respectively [1]. Lex Weaver researched on machine learning and in particular Temporal Difference Learning, and co-authored of the chess program KnightCap along with Jonathan Baxter and Andrew Tridgell [2].
