Reading the experiment

RBM: positive associations come from data and hidden probabilities; negative associations come from a CD-k reconstruction.

Full BM: the positive phase clamps visible data while the negative phase lets every unit run freely. More Gibbs steps generally reduce sampling bias but cost more time.

Temperature: lower values make states more deterministic. Edge width shows magnitude; green and red show weight sign.

Model behavior follows Ackley, Hinton, and Sejnowski (1985), with RBM contrastive-divergence controls based on Hinton's practical guide. Source links are in the README.
