Ile komórek LSTM powinienem użyć?

Czy istnieją jakieś praktyczne zasady (lub rzeczywiste zasady) dotyczące minimalnej, maksymalnej i „rozsądnej” liczby komórek LSTM, których powinienem użyć? W szczególności odnoszę się do BasicLSTMCell z TensorFlow i num_unitswłasności. Załóżmy, że mam problem z klasyfikacją zdefiniowany przez: t...

Czy są jakieś dobre gotowe modele językowe dla Pythona?

Prototypuję aplikację i potrzebuję modelu językowego, aby obliczyć zakłopotanie w przypadku niektórych wygenerowanych zdań. Czy istnieje jakiś wyuczony model języka w Pythonie, którego można łatwo używać? Coś prostego jak model = LanguageModel('en') p1 = model.perplexity('This is a well...
