Keras中嵌入件的输入层尺寸
我不清楚在以下示例中指定输入维度Keras中嵌入件的输入层尺寸,keras,embedding,Keras,Embedding,我不清楚在以下示例中指定输入维度input（shape=（20，）与不指定input（shape=（None，）之间是否有任何区别： input_layer = Input(shape=(None,)) emb = Embedding(86, 300) (input_layer) lstm = Bidirectional(LSTM(300)) (emb) output_layer = Dense(10, activation="softmax") (lstm) m
input（shape=（20，）input（shape=（None，）input_layer = Input(shape=(None,))
emb = Embedding(86, 300) (input_layer)
lstm = Bidirectional(LSTM(300)) (emb)
output_layer = Dense(10, activation="softmax") (lstm)
model = Model(input_layer, output_layer)
model.compile(optimizer="rmsprop", loss="categorical_crossentropy", metrics=["acc"])
history = model.fit(my_x, my_y, epochs=1, batch_size=632, validation_split=0.1)
my_xmy_yInput（shape=（None，）model.predict（my_x[：，0:10]）my_xNone
