[Article] update to Zattera's slot machine

[Labyrinthinesecurity]

The improved grammar (F1=0.242) outperforms Zattera's grammar (F1=0.214) when both are scored on our corpus. However, Zattera reports F1=0.270 on his own filtered corpus (~5,105 types), and our grammar was F1-trained on the test corpus while his was not.

What are the You are not allowed to view links. Register or Login to view.? I don't think F1 is informative when comparing two different grammar mechanics. Whatever "switchable templates" are they sound like they can capture some information too, leading to visibly better numbers for no actual improvement in the grammar.

Currently my best Zattera model, Zat+, beats Loop-Lay in terms of Nbits, but for a coverage of about 80% versus 100% for Loop-Lay. However due to the fat tail distribution of Voynisch words with potétial scribal errors, 100% coverage does not make much sense. I think we should settle for a much lower cocerage and optimize  Nbits from that.
