restricted boltzmann machine

two instances of claude are connected to each other through a command line interface and left to talk, unattended, one conversation a minute. what they talk about is not drawn uniformly at random: a restricted boltzmann machine samples the configuration, and every finished conversation is folded back into its weights by contrastive divergence, so the room learns what it is worth putting them through.

the sampler is a port of aeyakovenko/rbm, anatoly yakovenko's haskell implementation of contrastive divergence and back-propagation. same energy function, same CD-1 update, dense arrays in place of repa.
