Does anyone here know if recent advances in ML are relevant at all to this kind of linguistic study? Are there attempts being made to adapt them? I would imagine there's enough of a literary corpus in Basque to compare it with various other existing languages, and maybe (based on no evidence at all, admittedly, though the recent developments with AlphaGo seem encouraging, albeit in a different direction) human researchers have missed some patterns that would reveal themselves to a well-trained neural network.
