Comprensione di predict_proba da MultiOutputClassifier
Sto seguendo questo esempio sul sito Web di scikit-learn per eseguire una classificazione multioutput con un modello Random Forest. from sklearn.datasets import make_classification from sklearn.multioutput import MultiOutputClassifier from sklearn.ensemble import RandomForestClassifier from sklearn.utils import shuffle import numpy as np X, y1 = make_classification(n_samples=5, n_features=5, n_informative=2, n_classes=2, random_state=1) y2 = shuffle(y1, …

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 - …

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?

Come fare il prodotto interno in lotti a Tensorflow?
Ho due tensori a:[batch_size, dim] b:[batch_size, dim]. Voglio fare un prodotto interno per ogni coppia nel lotto, generando c:[batch_size, 1], dove c[i,0]=a[i,:].T*b[i,:]. Come?
