Forgive me, but I'm less impressed by the paper. As far as I can tell, they've only really shown that (1) language is recursive, which we know already; (2) markov models cannot capture recursive languages, which we've known; and (3) RNNs can, which we've known. But so can PCFGs and many other formalisms from the past 25 years, which they ignore.

I did not read it very closely though.

From the article:

> We can formalize the above considerations by giving rules for a toy language L over an alphabet A. In the parlance of theoretical linguistics, our language is generated by a stochastic or probabilistic context-free grammar (PCFG) [41–44]. We will discuss the relationship between our model and a generic PCFG in Section C.
