Shane Legg: Machine Super Intelligence (2008) [pdf]

This thesis explores the concept of universal artificial intelligence (AIXI) and its implications. It argues that AIXI agents can learn to perform optimally in a wide range of environments, despite having no explicit knowledge about them. The thesis also investigates the limitations of computable agents in approximating theoretical super intelligent models like AIXI. Additionally, it proposes ...

Evidence on the presence and history of assortative mating

https://media.springernature.com/w215h120/springer-static/image/art%3A10.1038%2Fs41467-024-47113-x/MediaObjects/41467_2024_47113_Fig1_HTML.png
Assortative mating – the non-random mating of individuals with similar traits – is known to increase trait-specific genetic variance and genetic similarity between relatives. However, empirical evidence is limited for many traits, and the implications hinge on whether assortative mating has started recently or many generations ago. Here we show theoretically and empirically that genetic ...

Consistency LLM: converting LLMs to parallel decoders accelerates inference 3.5x
