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...

Gere previsões ortogonais (não correlacionadas) para uma determinada variável

Eu tenho uma Xmatriz, uma yvariável e outra variável ORTHO_VAR. Preciso prever a yvariável usando X, no entanto, as previsões desse modelo precisam ser ortogonais e, ao ORTHO_VARmesmo tempo, estar o mais correlacionadas ypossível. Eu preferiria que as previsões fossem geradas com um método não...
