Variational Language Models
Definition
A variational language model uses local probabilistic units inside hidden computation so that uncertainty can be represented, propagated, measured and potentially used before the final output distribution is produced.
Research perspective
JWAYU investigates this approach through EVE units, controlled language-model experiments and internal diagnostics such as posterior variance, KL activity and mutual information.
