Abstract
The Restricted Boltzmann Machine (Smolensky, 1986; Hinton et al., 2006) has inspired much research in recent years, in particular as a building block for deep architectures (see Bengio (2009) for a review). The Restricted Boltzmann Machine (RBM) is an undirected graphical model with latent variables, exact inference, rather simple sampling procedures (block Gibbs), and several successful learning algorithms based on approximations of the log-likelihood gradient. However, when it comes to actually computing the distribution or density function, it is intractable, except when either the number of inputs or latent variables is very small (about 25 binary hidden units with current computers and about an hour of computing, on MNIST).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
