我正在构建一个线性回归模型，将一个 numpy 数组映射到一个 numpy 数组，
即[1.0,1.0,1.0,1.0] ---> [5.0,5.0,5.0,5.0]
我的网络如下所示，您可以看到 x 占位符对应于输入，y 占位符对应于输出。但是，我的模型只是收敛到 1.0:
import numpy as np
import tensorflow as tf
from tensorflow.keras.layers import Dense
g= tf.Graph()
with g.as_default():
x = tf.placeholder(dtype=tf.float32, shape = (None,4))
y = tf.placeholder(dtype=tf.float32, shape = (None,4))
model = tf.keras.Sequential([
Dense(units=4, activation=tf.nn.relu),
Dense(units=4, activation=tf.nn.sigmoid)
])
pred = model(x)
loss = tf.reduce_mean(tf.square(pred - y))
train_op = tf.train.AdamOptimizer().minimize(loss)
init_op = tf.group(tf.global_variables_initializer(),
tf.local_variables_initializer())
with tf.Session(graph=g) as sess:
sess.run(init_op)
for step in range(1000):
_ , lossy, predicted = sess.run([train_op,loss,pred], feed_dict = {x:np.ones(shape=(1,4)),
y:5*np.ones(shape=(1,4))})
print(predicted)
不幸的是，结果收敛到 numpy 的 ones 数组而不是 fives:

请您参考如下方法:
您不应使用 sigmoid 激活函数。请改用 RELU。 因为 sigmoid 函数将数字限制在 range(-1, 1) 范围内。
model = tf.keras.Sequential([
Dense(units=4, activation=tf.nn.relu),
Dense(units=4, activation=tf.nn.relu)
])
