The conference proceedings from the Artificial General Intelligence 2011 conference (AGI-11) have been published. See the intelligence explosion bibliography for a full list of its contents. The conference proceedings include several papers relevant to Friendly AI, including Yudkowsky’s “Complex Value Systems in Friendly AI” (confusingly, titled elsewhere as “Complex Value Systems are Required to Realize Valuable Futures”).
Yudkowsky will be giving a talk called “Open Problems in Friendly Artificial Intelligence” at the 2011 Singularity Summit in NYC.
