Query: The Grammar-Learning Trajectories of Neural Language Models   The learning trajectories of linguistic phenomena in humans provide insight
into linguistic representation, beyond what can be gleaned from inspecting the
behavior of an adult speaker. To apply a similar approach to analyze neural
language models (NLM), it is first necessary to establish that different models
are similar enough in the generalizations they make. In this paper, we show
that NLMs with different initialization, architecture, and training data
acquire linguistic phenomena in a similar order, despite their different end
performance. These findings suggest that there is some mutual inductive bias
that underlies these models' learning of linguistic phenomena. Taking
inspiration from psycholinguistics, we argue that studying this inductive bias
is an opportunity to study the linguistic representation implicit in NLMs.
  Leveraging these findings, we compare the relative performance on different
phenomena at varying learning stages with simpler reference models. Results
suggest that NLMs exhibit consistent "developmental" stages. Moreover, we find
the learning trajectory to be approximately one-dimensional: given an NLM with
a certain overall performance, it is possible to predict what linguistic
generalizations it has already acquired. Initial analysis of these stages
presents phenomena clusters (notably morphological ones), whose performance
progresses in unison, suggesting a potential link between the generalizations
behind them.
