ingrandisci la mappa di calore dei nati marini
Creo un corr()df da un df originale. Il corr()df è venuto fuori 70 X 70 ed è impossibile visualizzare il heatmap ... sns.heatmap(df). Se provo a visualizzare il corr = df.corr(), la tabella non si adatta allo schermo e posso vedere tutte le correlazioni. È un modo per stampare l'intero …

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 …

Relazione tra convoluzione in matematica e CNN
Ho letto la spiegazione della convoluzione e la capisco fino a un certo punto. Qualcuno può aiutarmi a capire come questa operazione si collega alla convoluzione nelle reti neurali convoluzionali? È una funzione simile a un filtro gche applica peso?
