Furthermore, the system of Pramanik and Hussain (2018) continues to make unrecoverable errors, though they do claim that their solution fails to make such errors in DATE examples like 11/10/2008; and while Yolchuyeva, Németh, and Gyires-Tóth (2018) do not report whether their system makes these kinds of errors, given that their overall per-class errors do not differ substantially from our own, it would be surprising if such errors did not occur.
it seems reasonable to conjecture that one is not going to eliminate the problem of unrecoverable errors by simply choosing a different model architecture.
