Quantas células LSTM devo usar?

Existem regras práticas (ou regras reais) referentes à quantidade mínima, máxima e "razoável" de células LSTM que devo usar? Especificamente, estou relacionado ao BasicLSTMCell da TensorFlow e à num_unitspropriedade. Suponha que eu tenha um problema de classificação definido por: t - number of...
