我在tensorflow網站上發現了一些示例代碼,如下所示。機器學習中的「培訓損失」是什麼意思?
input_fn = tf.contrib.learn.io.numpy_input_fn({"x":x_train}, y_train, batch_size=4, num_epochs=1000)
eval_input_fn = tf.contrib.learn.io.numpy_input_fn({"x":x_eval}, y_eval, batch_size=4, num_epochs=1000)
# We can invoke 1000 training steps by invoking the method and passing the
# training data set.
estimator.fit(input_fn=input_fn, steps=1000)
# Here we evaluate how well our model did.
train_loss = estimator.evaluate(input_fn=input_fn)
eval_loss = estimator.evaluate(input_fn=eval_input_fn)
print("train loss: %r"% train_loss)
print("eval loss: %r"% eval_loss)
你能告訴我'培訓損失'是什麼意思嗎?
非常感謝! –
