The Garden of Forking Paths: Observing Dynamic Parameters Distribution
  in Large Language Models
Carlo Nicolini Jacopo Staiano Bruno Lepri Raffaele Marino
A substantial gap persists in understanding the reasons behind the
exceptional performance of the Transformer architecture in NLP. A particularly
unexplored area involves the mechanistic description of how the distribution of
parameters evolves over time during training. In this work we suggest that
looking at the time evolution of the statistic distribution of model
parameters, and specifically at bifurcation effects, can help understanding the
model quality, potentially reducing training costs and evaluation efforts and
empirically showing the reasons behind the effectiveness of weights
sparsification.
