Perché xgboost è molto più veloce di sklearn GradientBoostingClassifier?
Sto cercando di formare un modello di aumento gradiente su 50.000 esempi con 100 funzioni numeriche. XGBClassifiergestisce 500 alberi entro 43 secondi sulla mia macchina, mentre GradientBoostingClassifiergestisce solo 10 alberi (!) in 1 minuto e 2 secondi :( Non mi sono preoccupato di provare a far crescere 500 alberi perché …

Quante celle LSTM dovrei usare?
Esistono delle regole empiriche (o regole effettive) relative alla quantità minima, massima e "ragionevole" di celle LSTM che dovrei usare? In particolare mi riferisco a BasicLSTMCell di TensorFlow e num_unitsproprietà. Si prega di supporre che ho un problema di classificazione definito da: t - number of time steps n - …

Esistono buoni modelli linguistici predefiniti per Python?
Sto prototipando un'applicazione e ho bisogno di un modello linguistico per calcolare la perplessità su alcune frasi generate. Esiste un modello di linguaggio addestrato in Python che posso usare facilmente? Qualcosa di semplice come model = LanguageModel('en') p1 = model.perplexity('This is a well constructed sentence') p2 = model.perplexity('Bunny lamp robert …
