The Boltzmann brain gained new relevance around 2002, when some cosmologists started to become concerned that, in many theories about the universe, human brains are vastly more likely to arise from random fluctuations; this leads to the conclusion that, statistically, humans are likely to be wrong about their memories of the past and in fact ...
Ludwig Eduard Boltzmann (/ ˈ b ɒ l t s m ə n /, [1] US: / ˈ b oʊ l-, ˈ b ɔː l-/; [1] [2] German: [ˈluːtvɪk ˈbɔltsman]; 20 February 1844 – 5 September 1906) was an Austrian theoretical physicist and philosopher. His greatest achievements were the development of statistical mechanics and the statistical explanation of the second ...
A Boltzmann machine (also called Sherrington–Kirkpatrick model with external field or stochastic Ising model), named after Ludwig Boltzmann, is a spin-glass model with an external field, i.e., a Sherrington–Kirkpatrick model, [1] that is a stochastic Ising model. It is a statistical physics technique applied in the context of cognitive ...

[3]: 2 For example, observers in a Universe of 13.8 billion years old (our observed age) are outnumbered by observers in a 13.0 billion year old Universe by a factor of . This lopsidedness continues, until the most numerous observers resembling us are "Boltzmann babies" formed by improbable fluctuations in the hot, very early, Universe.
It just states the process of evolution, which is beside the point: The Boltzmann brain is a counter to the anthropic principle, showing that selection bias means we should expect a Boltzmann brain universe rather than our vastly more complex universe. ··gracefool ☺ 13:44, 30 May 2014 (UTC)
Diagram of a restricted Boltzmann machine with three visible units and four hidden units (no bias units) A restricted Boltzmann machine (RBM) (also called a restricted Sherrington–Kirkpatrick model with external field or restricted stochastic Ising–Lenz–Little model) is a generative stochastic artificial neural network that can learn a probability distribution over its set of inputs.
